3030 extrusions quick fastener - fits Prusa i3 MK3!

A print-in-place quick fastener for 3030 aluminum extrusions! Just put in in the slot and twist 90 degrees and you can fasten things to 3030 extrusions without disassembling half of the printer. Great for things that needs to come off for transport or any other reason such as spool holders on top or fragile webcam arms.

This thing is meant to be used in other models, thus the STEP-file that you can import into Fusion360 or whatever software you use and incorporate into your design. I also uploaded two test .stl-files with and without support blocks under the "wings" of the screw. I have tried with 3030 extrusions from 3 different manufacturers and they all seems to work well with this part, if you have any problems please leave a comment and maybe upload a remix that worked for you! :)

Printer Brand:

Prusa

Printer:

Yes

Resolution:

Notes:

Printing this in PLA can sometimes be a bit to brittle when it comes to removing the supports and twisting the screw. PETG seems to work well and allows for some flex when turning the screw.

Post-Printing

1. Carefully remove support-blocks if used
2. Push the wing-part towards the screw-part to make it come loose before twisting.
