Sliding block nut for Geeetech A20M

thingiverse

To improve my new Geeetech A20M with a Raspberry Pi I've designed a new holder (https://www.thingiverse.com/thing:3470418) for the Anycubic i3 MEGA Raspberry Pi case for OctoPrint by FischC (https://www.thingiverse.com/thing:2754779). I had the problem to fix it at the side of one profile because I didn't even know the name "sliding block nut", so it was very difficult to search for :) That's why I've made one with FreeCAD. This part has not exactly the same size, because I've decided to use a metal nut in the middle to fix the screw. The shape as well is not identical, but it works. I tried to print it with my new printer, but somehow the profile of my Geeetech was not good enough at that moment. So I used my old Anycubic i3 Mega and it worked well with standard PLA. Now I use it in the way that I take one of the originals from my printer and one of my selfmade ones. I would not recommend to use only the selfmade ones if there is much weight to hold - like for instance the spool-holders on the top - because your printer could be damaged if they break.
