Ender 3 side spool bracket
thingiverse
I was on the hunt for a side mount bracket and this one seemed to fit the bill, but I ran into some issues with the part's fitment. The screw hole sizing wasn't quite right and it was loose on the rail when mounted. To get around these problems, I reworked the design in Fusion using a 3D model of the extruded rail from my Ender 3 base to ensure a tight fit. I also made sure that the screw holes would self-tap into the original screws. I printed it out with Ziro Carbon Fiber PLA so that it would be stiffer and look cool. To be honest, I'm not sure if it needs to be angled to reduce tension on the filament, but so far, I haven't encountered any issues.
