Prusa i3 upgraded spool holder

thingiverse

I found that standard filament holders for Prusa i3 Mark 1 and Mark 2 were subpar as changing rolls of filament was very annoying and did not fit all rolls I owned. This will also work for MK3, as they share the same frame. I simply improved on the original design by replacing knobs used to hold filament with a pocket and creating a long rod from a cylinder matching knob dimensions. This allows you to place arms permanently on your printer and lift up on the rod to replace rolls of filament. The design also allows you to fit two standard 1kg rolls or 3-4 rolls of .5 kg filament, but I'm not certain because I don't own any rolls that size. Hopefully this design saves you frustration and provides easy roll replacement. Print Settings: Printer Brand: RepRap Printer: Prusa i3 mk2 Rafts: No Supports: No Resolution: Low Quality Infill: %50 Notes: You need to use a brim when printing or the rod will not stick to the print bed, as it is very tall. Be gentle with the rod when taking it off of the print bed, as it can snap in half when tugging on it but does not have any issues holding the weight of the roll(s).
