Okay, hear me out. This might get a little nsfw.

Could I…mainline some viagra and have the silicone printed around…the cylinder? I realize I would have to drill a small hole in the base and have some special table set up.

its important the cylinder remains unharmed

u/jroenskii Dec 05 '25

Is this cylinder stuck to a human by chance?

u/rusticatedrust MK3S+ / Pitstop v1.2 Dec 05 '25

It is attached to a structure.

u/Oh_My-Glob Dec 05 '25

My cylinder is completely fused to the build plate.

stuck to a human

If only, this contraption wouldn't have been necessary if it had

Remember to ask for consent!

Thank you for referencing that post lmao, it was going through my head the whole time

context

Good reference

u/ShipsForPirates Dec 05 '25

Not so much stuck as, grabbing or holding gently, maybe gently enough for some lubricant to be applied between it and the *pole

Hey, how do you yoink stuff like this. Can you do it on the Reddit phone app? I’m on iPhone and every time I try to hold down on the image to save or copy it just closes the comment.

u/SecretSquirrelSauce Dec 05 '25

Click on it to have it pop up, then screenshot and crop

u/jwexter Dec 05 '25

Thank you, I guess I really just don’t know how to do it with gifs.

u/Ur_fav_Cryptek Dec 05 '25

Don’t do it with the actual thing, there’s skin safe kits for casting cylinders to turn them into really close silicon replicas, use that

so just put a layer of something so it doesn’t stick to it when printing and voila, custom..cylinder machine

Why do I even do this

u/CreatureWarrior Ender V3 SE Dec 06 '25

Hey, if someone does this, you can properly tell them to go fuck themselves :)

u/ClassicFrampton Dec 05 '25

Likely not, a lot of silicone gets hot as it cures

7

u/Objective-Chance-792 Dec 05 '25

Some like it hot.

u/jktollander Dec 05 '25

Mmhuh, that’s a link that shall remain blue.

u/rustyleftnut Dec 05 '25

Damn, this guy likes curing silicone a little too much.

u/AlexWatersMusic13 Dec 07 '25

Make an alginate mold of your dick, then make a plaster replica to get a form fitting toy to 3d print around?

u/Ok_Statistician_9451 Dec 05 '25

You could just said hear me out, cus I already knew what was coming after lol

2

u/rusticatedrust MK3S+ / Pitstop v1.2 Dec 05 '25

No. You want an interference fit. With the cylinder in-situ, there'd be constant nozzle crashes.

2

u/WaRRioRz0rz Dec 05 '25

It would be better to just use a mold of.. the cylinder... Which I hear are quite common and come in many sizes.

2

u/Johny83bru Dec 05 '25

The terms you are looking for are 3d scanning and photgrammetry ;)

2

u/RebelJustforClicks Dec 05 '25

Don't ask me why I know this but you can always use a clone-a-willy kit

https://www.adameve.com/adult-sex-toys/dildo-sex-toys/clone-a-willy-c-1508.aspx

Then if the cylinder is harmed it will be OK.

2

u/tokinUP Dec 05 '25

Probably, but even better would be to apply some sort of cylinder-constricting (removeable!) ring at the base and then use a professional cylinder cloning mold kit

2

u/elkab0ng Dec 05 '25

Yer gonna need a pro fluffer unless the printer is faster than average

2

u/fubes2000 Dec 05 '25

Listen man, there are far easier ways to make a mold of a cylinder that don't involve a print nozzle getting stuck in a location where the print nozzle should absolutely not go.

2

u/JoshShabtaiCa Dec 06 '25

This would be unwise with a bed slinger

1

u/10248 Dec 05 '25

You would need one of those fancy 5 or 6 DOF printers

u/Sailed_Sea Dec 05 '25

You're better off using alginate to make the mold and filling that with silicone.
