Prusa i3 MKII Spool Coaster Tray
thingiverse
I needed a more effective solution to the spool mount on my Prusa i3 MKII. The Spool Coaster from Printrbot delivers nearly frictionless spool rotation. This tray holds the Spool Coaster and ejects the filament just above the extruder. The holes in the tray are clearance for 10mm screws, three of them. The holes in the mounts are sized so screwing in a 3mm metal screw will create threads. Fabricated using Atomic Filament Gun Metal Gray PLA at 210C, with the bed set to 55C. The wall thickness is 2mm all around, and I used 15% infill.
