Double ultimate filament holder for Prusa i3 mk 2

thingiverse

Edit (20th June 2017) - small tweak to the model: The top spool holder cutout has been smoothed out to eliminate a stress riser where it often snapped after an impact. The top spool holder is now mostly hollow, making it more rigid. A vertical arm has been designed with a cutout for added lateral rigidity later on. G-code file included for printing in ABS on an I3 MK2. Filament holder for holding two spools atop a Prusa I3 MK2 printer. Ideal for multi-color prints where filament needs to be changed mid-run, or just for storing an extra roll nearby. A follow-up to my previous cantilever filament holder can be found here: http://www.thingiverse.com/thing:1808217 Print Settings: Printer Brand: RepRap Printer: Prusa I3 MK2 Rafts: No Supports: No Resolution: 0.2mm Infill: 30% Post-Printing: Assemble the print by gluing two parts together back-to-back using included pegs. CA glue (superglue) works perfectly for flat PLA surfaces like this. How I Designed This: Created in Freecad
