Adjustable Spool holder Stops

These parts were designed around the Adjustable spool holder by KERLE MAKERSPACE.

I wanted a nice clean look for the adjustable spool holders inside my 3D Printer Enclosure and have a stop to keep the parts from completely sliding off the rails. I designed these parts to use M3 flat screws and M3 nuts to give it a nice clean look. I printed it with 0.2 Layer height with PETG filament and 0.4 Nozzle. No supports are required.
