Filament roll holder for Prusa 3d printer

thingiverse

This is a very easy to use filament roll holder that simplifies loading and unloading of rolls for your printer. Just set the roll on the 4 wheels and you are ready to feed the filament into the print head. The plastic side pieces clip on to the printer frame in a similar fashion to the roll holder arms delivered with the printer. You need 2 supports and 4 v-groove wheels for one roll. This design uses 3/8" metal rod, the supports use a friction fit to the rod to keep it in place. The length of the metal rods allows you to design it for 1 or 2 rolls, just add 4 more wheels for a second roll. Print Settings Printer: Prusa i3 MK2 Rafts: No Supports: No Resolution: 0.2 mm Infill: 10% Notes: Wall thickness and infill not critical... no high-stressed parts. I used PLA for the one in the photo, with side walls 3 passes and 4 layers for top and bottom surfaces.
