Description

This is the magic piston. It works by using two magnets which are either a 8x3 or 6x3 set with the same pole facing each other, so instead of attracting, they push away. That resistance keeps the piston from going down easily, making it feel like it’s floating or pushing back when you press on it. Assembly for the magic piston is very simple. Just make sure both magnet are facing the same pole so they repel. If you want the button to pop up higher I would recommend to use 8x3 magnets. For easier sliding you can sand down the bottom edge of the piston.

8x3 Magnets

fun toy! ended up using three 8x2 magnets on each side and sanded down the inside of the tube and the rod itself and now it works great

Great! I’m glad it worked for you.

@king_kailing

how did you sand the inside?

@TurboTime32

Replying to @king_kailing :

took a piece of sanding paper and rolled it into a tube and rubbed that along the inside

@king_kailing

6x3 cap does not screw in

The designer has replied

@24_crazycats

Hi, to get the threads working properly you have to push decently hard to get the cap started then screwing the cap should be easy to use after broken in.

Replying to @24_crazycats :

let me try this again, I think I have already tried it but thank you!mi will keep you posted

@king_kailing

Replying to @24_crazycats :

it seems that one side screws in a little lopsided, and it is very hard to screw in. should I just print another one?

@ddduuurrrrrrrrr

I stuck ot up my you know what dont do it im on the er now

@user_418638667

wha

@jackeroni

doesn’t say size of my magnet can you send a pic of a comparison next to a penny of both magnet sizes? Thanks 😊

The designer has replied

@24_crazycats

See if these work for ya. If not it would be a good idea to grab a some calipers for 15 bucks to get a clean accurate measurement.

Replying to @24_crazycats :

Thanks

@joshgoreprints

so I printed this twice on my A1 mini. both times the screw on cap was to small to screw onto the tube :(

The designer has replied

@24_crazycats

It is hard to get it started sometimes so you have to push very hard while screwing. Then it should work.

@joshgoreprints

Replying to @24_crazycats :

thanks man. got it!

@user_2268164626

does not work

The designer has replied

@24_crazycats

I would make sure magnets are repelling. The description says it is also smart to sand the bottom edge of the piston. If any other issues persist please give me more context to help.

@user_2268164626

Replying to @24_crazycats :

thanks

@Hotcole_

but the real one uses air pressure 🥲 still pretty cool.

The designer has replied

@24_crazycats

Totally true! But a regular 3D printer a is not capable of clearances that close

6x3 Magnets

printed fine but piston didn’t pop back up

The profile uploader has replied

@24_crazycats

All you need to do is sand the piston and the bottom edge

(Edited)

@Noobmaster

did you get the idea from the memo piston

The designer has replied

@24_crazycats

Yes, inspired by the metmo piston.
