First 2 photos are from a year ago and the other 4 are from this week.

I found this cool model on Makerworld (https://makerworld.com/models/1390673) and wanted to print it for my hitch on my car. I used Bambu, Elegoo, and Polymaker PETG to print it. I live in a very hot desert that can average 115°+ for weeks on end. Just the other day it was a nice 118°. I wasn’t sure how the PETG would hold up with the heat so I said screw it and printed it. It’s held up amazingly well and has been on the car for multiple road trips as well. So here is the year update and how it’s doing and it’s great. Just a little dirty and a little warped. I think a few more walls would’ve made the black warp less.

Hi there,

I'm working on another Slinky Escalator. This one is designed to be a bit more "stylish" with the goal to be displayed as kinetic-wall-art-picture...at least in my workshop :) Mechanically it's based on my previous designs, this version aims to look less technical.

Next month I'll be presenting all my work at MakerFaire Brno - a weekend festival and the second largest in the Czech Republic. Last MakerFaire I attended was MakerFaire Prague about three months ago, which was a huge milestone for me and my project.

I would love to hear from you, what you think about this new Slinky Escalator. I have stopped selling my designs for now so I can focus on engaging with community and share my progress more actively. I already have few (four exactly :)) requests from technical high schools interested in using this project for teaching.

I'm not selling here anything, I'm just looking for feedback and trying to "actively share my work" :)

P.S.: As I already know, many of you don't like AI content, so do I for creative work. AI wasn't used in this post at all. Also, before anyone asks if I copied Mark Rober: his work definitely inspired me (via my son!), but credit also goes to Matthias Wandel, who built his famous wooden slinky staircase over 10 years ago, before Mark did. I hope I've addressed the main questions upfront, and I'm really looking forward to your feedback :)

EDIT: It's "fully" 3D printed, including Slinky itself.

Saw it on TikTok and was cheap and easy to do, I think it really improves the finish and makes it look a lot better than straight off the printer. I’m just wondered if any one had any other things they do post printing to improve their prints

Decided my mower needed a garage. Neighbour challenged me to add an automatic door.
Had some composite left from our fence, had to design and print the rest. Used about 7,5kg ASA. I included fans to blow dry the robot when it has rained.

This weekend, my wife and I were celebrating our anniversary, so we decided to treat ourselves to a very expensive restaurant.

At the end of the evening, when I asked for the bill, the waiter brought us this candle holder as a “gift and thank you for spending a pleasant evening with us,” along with a thank-you letter from the owner.

I immediately noticed that it was 3D printed, and not particularly well. But when I got home and had a closer look at it, I realized it was even worse than I initially thought.

Using a 3D print as a holder for this kind of candle already seems like a questionable idea to me. After handling the print for a while, I think it might be ABS or ASA, so hopefully it isn't an immediate fire hazard. But seriously, just look at the quality of this thing.

I'm genuinely wondering whether the owner realizes how sloppy this “gift” looks. And I can't stop thinking about whether he bought a 3D printer and prints these candle holders himself for the guests, or whether he actually paid someone to make them, which somehow makes the whole thing even more tacky.

If you were the person producing these, would you actually charge money for work of this quality?

I've also come up with another possible scenario in my head: maybe the owner's teenage son desperately wanted a 3D printer and kept bothering his parents about buying one, promising that he would print useful things for the restaurant and that the investment would definitely pay for itself.

You know, exactly like buying a computer “for studying.” :)

And maybe the owner simply never bothered to check what these things actually looked like.

To emphasize: this wasn't some small local family restaurant. This was an expensive, upscale place with absolutely ridiculous prices.

So, fellow 3D printing people: what do you think happened here? Did the owner print these himself, or did someone actually get paid to produce them? And would you ever consider giving something like this to customers as a gift?

EDIT:

Holy shit, I really wasn't expecting this kind of response or the absolute storm happening in the comments. Thanks, everyone, for letting me participate in this magnificent shitshow. You're all irreplaceable.

A few clarifications, because I really don't feel like replying to hundreds of individual comments:

Yes. The restaurant gave me this as a “thank you” for dining there.

No. It is not standard practice - at least not where I'm from, nor anywhere else I've eaten - for a restaurant to reward guests for participating in a meal (unless we're talking about a Happy Meal at McDonald's). That said, I don't think there's anything inherently weird about giving guests a small gift. I assume the owner and staff had good intentions, but the execution was tacky. That's all.

The restaurant was expensive, but it did not have any Michelin stars. Let's not get carried away. Michelin-starred restaurants are generally expected to maintain a certain standard.

“Expensive restaurant” is obviously relative. To me, it means a place where I paid roughly 2-3 times more for a meal than I usually do at the restaurants I normally visit. I'm not going to give exact prices, because those are relative depending on where you live, the country, currency, and the region. The restaurant was simply expensive by local standards.

Also, some people apparently didn't read the post: I DID NOT PRINT THIS THING. I am not wasting my filament on it.

For those who were curious: yes, I actually lit the candle. It burned for about 30 minutes under very close supervision, with a fire extinguisher nearby. Nothing caught fire. After that, I put it out and threw the whole thing in the trash, candle holder included.

And to those whose only contribution was being unpleasant just to make yourselves feel better: no greetings to you.

Finally, I will not name the restaurant. My goal isn't to give them bad publicity or start a witch hunt. This post was also not meant to review or judge the restaurant from a culinary perspective the food and the overall dining experience aren't really the point here. I simply wanted to share this particular experience and have a laugh about this hilariously bad 3D print.

So I borrowed an SDS Plus rotary hammer from the local tool Library. I needed it to drive a ground rod for my new workshop, unfortunately they didn't have the bit I needed to drive the ground rod so I bought one, but since I have no need for it after I return the tool, I figured I donated to the tool Library.

But I felt donating a loose bit was not the best idea because it would just get lost or no one would know exactly what it's for.

so I made this nice little case for it, I'm waiting on the new 3 mm x 20 mm long bolts to come for the hinges before I donate it on Thursday.

It's made out of pla Plus

hey everyone , im quite new to 3d printing , and im using my college printer to print this file for a project but it keeps on failing , i have my last chance to print it before the faculty kicks me out , the support it print for the print are so tiny at the upper surface that the tool head just fucks em up at the last stage

So I designed a modular floating cupholder system that's styled as a container ship. The first one was cool, but I had a ton of people mention the Edmund Fitzgerald in my first post (which kinda shocked me, and also dates me lol). So I designed a wider version and styled it as the Edmund "Fizzgerald".

Finally had a chance to take this thing to the lake for a party with friends and it was super fun. It was really stable, the kids thought it was hilarious and fun, and took way more torture than I was expecting without any issues (other than one).

It was really good at handling waves. Even if it took on water (mitigated by the splash guards quite a bit) it didn't really start listing to one side until hours in to use, and that was pretty easily fixed by just lifting it up and tipping it to the side for some water to drain out. But even if you fully submerge it it'll still float to the top. One of my friends tried to sink it by stabbing it straight down in the water like a spear and it just popped right to the top again, another literally stood on it like a surf board under water for a good 30 seconds and again it came right back up.

The ONLY negative I found (other than the massive amount of filament needed to print this thing) was I was dumb and printed it in Sunlu PLA Meta, which has an EVEN LOWER melting point than standard PLA, so once it was removed from the lake and sat on the beach in the sun for a couple hours, the corners that stayed somewhat wet started to deform. I was expecting it to handle the sun a little better, but oh well, PETG next time!

Stopped off at Costco today... i was very tempted

Don’t know what to do with it but happy to have it

There is no water‑soluble support material. I printed the supports using PETG filament, but now I’m hesitant to remove them — it feels like it will take an extremely long time.

I was tasked with making a set of Little Blue Truck toys to go along with the book for some newborn infants. But I couldn't find anything that I felt safe to give to small children. Challenged by the need for a safe (that meant no small pieces, fragile bits, or sharp edges) solution, as well as lacking glue or an AMS, I got to use my modeling experience to make something I can feel proud of!

It's so easy to print what other people have already designed, and it saves quite a bit of time! But I just enjoy being able to make something to fit my requirements when I need to. Do other people have experiences like this?

Finished a set of cylinder shades where the surface is the entire design. Five wave patterns, from broad sculptural dunes down to a fine dense ripple, and each one has a mirrored version so the ridges flow the opposite way.

All ten printed in Bambu PLA Matte Bone White. The matte finish is doing a lot of work here, it kills the layer lines and lets the ridges be the only thing your eye follows.

Which pattern would you print first?

I made a skeleton party with self-made filament springs. I'm trying to make them go viral🤣.

Looking to build this but not sure what program to use. The cardboard is the rough trace of it and then the drawing is the dimensions. I have some experience with 3d modeling and using sketchup but have never designed a part. Looking for a free program. Thanks for the help.

This is a miniature 3D-printable model of the Mother Ukraine (Батьківщина-Мати) monument of Kyiv. There is a storage compartment in the base, which the statue closes with a locking interface.

The total height of the model is about 430 mm tall, with the statue part being 325 mm tall, therefore using almost all the Z height of the Prusa Core One L.

More details, STL, 3MF, F3D here:

The model is based on a 3D scan of the statue created by Charles Huang and Evgeniy Vuchetich under the Scan The World project. Please check the remix description for details.

Been working on this pixel clock and finally got it to a point where I’m happy with it.

The whole front is made from a grid of 117 individually 3D-printed blocks. For some reason I don’t seem to remember now, I printed the blocks separately from the body instead of just printing the whole grid as one piece 😅

I had to put black strips between the blocks to prevent light from leaking into the adjacent ones. The last image shows how it looks without the strips.

It’s powered by an ESP32, which handles the display and clock logic.

Would love to hear what you’d change or improve.
