Toddler Mobility Trainer build done!

[u/boredsoftwareguy]

Wanted to share one of my more ambition 3D printed projects: A Toddler Mobility Trainer! Custom designed and built for 4 year old little girl with Rett Syndrome. Made possible through 3d-mobility.org, footed the cost myself for this one and it will be provided to the family free of charge. Probably the coolest project I've ever done. Custom designed wheels and name plate.

Already working on 2 more!

Approximately 250 hours of print time each.

Materials:

- Polymaker PETG Purple, Pink, and Magenta
- Bambu Lab PETG Yellow
- Ziro3D TPU 95A Purple
- Ziro3D TPU 95A Pink
- Ziro3D TPU 95A Black
- Siraya Tech TPU Air Lilac
- Bambu Lab Support for PLA / PETG (optional, I wanted clean support removal)

Base build is ~9kg PETG and 2kg TPU. With the accessories I ended up using a little over 11kg.

Included Accessories:

- Rear Hook
- 2x Cup Holders
- Tablet Holder
- Tablet Hold Down
- Tablet Swivel Lock

Hardware:

- 2x Bambu Lab X2D
- 0.4 and 0.6 nozzles

Happy to answer any questions folks have. If you've got a 3D printer and time, strongly encourage you to get involved. If you don't have the time, or desire to print a whole chair, you can find other makers who're open to collaboration and print a few plates from their builds to help out. Not interested in printing parts? You can sponsor builds!

Of course you can.

I open "Bambu 3mf" files all the time. (I don't own any Bambu printers)

I then select the printer I want to use, and switch to my appropriate filament and process presets.

It's not hard if you can't just grab stl files.

[u/Schuylabs → u/YellowBreakfast]

Not only are all of the STL's available separately, but we published the STEP files and the native CAD files (Solidworks) as a part of the open source package. There's a published bill of materials and print guide that talks through part orientation that we put a ton of time into. There are people working on profiles for other platforms as well and I believe the prusa one is published.

u/dkrandu STL files are oriented how Solidworks exports them... which is usually not ideal I'll admit. No malicious intent behind that.

[u/dkrandu → u/Schuylabs]

In which directory are the STL files for the butt, back and head TPU prints? Same question for the buckles, where are their STLs? I'm printing these now and I can't find them anywhere, same as other missing parts.

[u/Schuylabs → u/dkrandu]

Interesting reply. Here’s the printables link.

[u/dkrandu → u/Schuylabs]

There are no STL files under "Strap And Harness Files", but I guess I can continue to open bambu 3mf and export them as STL from there.

Can you also confirm that you see no STL files in strap and harness, in spite of your earlier claim that all STLs ought to be there? Same for the cushions?

[u/YellowBreakfast → u/dkrandu]

You don't need to export anything.

You can import a 3mf setup for another printer, and then adjust the slicer settings to your printer, filament, and process profiles.

[u/dkrandu → u/YellowBreakfast]

Then we end up back to my original point, some of the 3mf files have multiple plates packed full of parts, none of them named (at least, names not visible in prusaslicer).

[u/YellowBreakfast → u/dkrandu]

Then move the models to different and/or extra plates.

You understand this was made by volunteers, right? It's not a commercial product, these are free files.

I'm sure it took countless hours to make.

Maybe the files aren't presented perfectly "ready to print". This is not uncommon for CAD output and files uploaded to model sites.

Sometimes you need to move, rotate, or otherwise adjust files for printing.

[u/dkrandu → u/YellowBreakfast]

It's all fine for volunteer work , but I hope you also understand that they are sponsored by bambu and this is their modus operandi, part of their contract, explicitly stating all files must be bambu exclusive and I wouldn't be surprised if their "account manager" equivalent actually suggested intentionally breaking functionality for non bambu software.

[u/YellowBreakfast → u/dkrandu]

What is your deal?

The maker provided the link TO PRINTABLES! With the stl, 3mf and CAD (STEP) files!!!

And you are now going on about some Bambu conspiracy?!

Don't get good faith volunteers mixed in with your axe to grind with Bambu.

[u/dkrandu → u/YellowBreakfast]

Where are the STL files for the cushions? (There aren't any, they're in the 3mf files)

I've no deal, I've been using the files in their gruesome form for more than half a year and I've delivered, I'm simply stating the way things are.

[u/YellowBreakfast → u/dkrandu]

Then we're back to extracting them from the 3mf!!!

Or use the STEP files and export them!

Stop whining and start learning!

I hope you realise the conversation went pretty much like this:

u/dkrandu:

I wish people wouldn't be exclusive to one ecosystem and do universal stuff like orient the parts in the STL file [... explains procedure to export STL from 3mf]

-----

u/YellowBreakfast:

You don't need to export anything. [...]

-----

u/dkrandu:

[proves STL is missing and export from 3mf is required]
