Prusa i3 MK3 Cable Chain Electronics Box 1.75mm Filament

thingiverse

The original version of this electronics box uses 3mm filament for support on two of the cable chains, but most people don't have 3mm filament. So instead I just loaded the file into Blender (it had too many vertices for Fusion 360 to convert to a BRep), and shrunk the 3mm filament holes down to 1.75mm. I also included a little "adapter" since the hole in the back of the x-axis chassis is meant for the 3mm nylon filament included with the printer, to allow you to hopefully get the filament in there without having to re-print the chassis with a smaller hole. Of course this is totally optional, and I'm sure you could get away with any number of other methods for making it work.
