Spool holder for original Prusa i3 MK2

thingiverse

I'm absolutely thrilled with my original Prusa i3 MK2, it's a real showstopper! Nevertheless, I have to admit that the stock spool holders just aren't doing it for me - they're lacking in my book. So, I decided to take matters into my own hands and create my own custom solution. My design is significantly thicker than the original part, which gives it a bit more heft and stability. Instead of relying on integrated plastic bolt stubs, mine has holes that can accommodate any 10 mm rod - I personally use steel for added durability. The holding arm also features a 2.7 mm hole from the bottom, allowing you to screw in an M3 screw to secure the spool holder firmly onto the i3 frame. To tighten it up, I simply use M3 Allen screws and give them a good hand-tightening - works like a charm every time!
