Improved Spool Holder Prusa i3 MK2/MK2S/MK3

thingiverse

This redesign of the MK3 spool holder is a significant improvement over the original. Using Fusion 360, I created a new frame clamp by extruding it, which also included adding a filament guide. The hole diameter is precisely 5mm, ensuring that it will accommodate 3mm filament perfectly. The redesigned holder securely snaps into place and stays put, without any movement at all. Printing this design was incredibly easy and straightforward. After printing, I found that the entire process took approximately 2 hours and 11.5 minutes to complete.
