Works great on my Prusa i3 MK3S.

Used for the screen flat cable and my Raspberry Pi camera flat cable.

Good news then! I'm not using my Raspberry attached to the MK3s printer so I not tested it until you check it! Thanks for your feedback!

I printed this and it is really loose in the aluminum profile. Is it supposed to rattle when twisted into place?
Printed in Prusa orange PETG. 0.2mm.


After installing all 10 to the aluminum profile on the left of the printer and then taking one and sticking it on the right side I find the right aluminum profile to be tight. No movement once twisted into the correct place. Perfect contact to keep the ribbon cable in place without rattling.

Does anyone else have this issue?
I have a Prusa i3 MK3.

Hello again. Sorry for been late with this answer. Finally I've printed 9 pieces of this part in Prusa PETG Black and fits really well inside the aluminium profile. There are no problems for use it in the MK3 / MK3S.

No problem. Sorry, I didn't explain my theory that my MK3 profiles are not a consistent size. Nothing to do your model being wrong.
On the left extrusion they fit loosely. On the right extrusion they fit nicely.
I haven't had an issue so far with them being rattly during use when using more than one clip on the left extrusion.
I think it's just that one clip when used individually, doesn't hold very well on the left-hand side of my printer.

I have an idea on how to make this model more resilient to tolerance changes by adding a small bump in the middle of the surface where it comes in contact with the internal extrusion profile surface but I cannot execute this idea without access to a file that can be edited in Fusion360.

I'll check it soon. In my case, this clip fits really good in my MK3 profile as you can see in the photography. Thanks for your comment.

Worked great, thank you for posting. Now my ribbon cables look much more organized! Prusa should ship these with the i3 mk3.

Thanks for your comment. It's very easy design and very useful for our MK3 printers. In my opinion is much better organize the LCD ribbon cables like this.
