Thanks for the design and well documented tutorial. Apart from some broken wire connections that took an evening to debug, it works well.

What is the source and part # for the pushbutton Switch?

I found a typo in the scad file for all the nut traps:

translate([0,-m3_nut_diameter_bigger*cos(180/6)/2,-mount_t+2])

It's suppose to be:
translate([0,-m3_nut_diameter_bigger*cos(180/6)/2,-mount_t-2])

Just need to reprint the brackets and panelmax is complete =D

Can you explain what's the error_factor and mount_thickness, since they're not defined in the scad file, or do they mean exactly what their name is?

Can you use the mounting nut on the rotary encoder if you attach it to the panel first, then solder the pcb on later?

OPENSCAD told me "Object isn't a valid 2-manifold! Modify your design.." when i tried to export to STL.

I had to readjust the path to the configuration.scad file which comes the prusa files.

Hope that helps someone

So nice ! I had been looking for a decent panel case for my ultipanel-compatible LCD+click encoder setup for a while. Since I had no use for the reset button I just removed that part from the scad and regened the STLs (probably did it wrong -- I guess I made the left front and right back, or the other way around, but it's still fitting well after a tiny bit of Dremelling). Thanks :)

Printed: Next - soldering.
