Prusa i3 MKII Spool Coaster Tray

I wanted a better solution to the spool mount on the Prusa i3 MKII. The Spool Coaster offered by Printrbot provides near frictionless spool rotation. This tray holds the Spool Coaster and discharges the filament just above the extruder.

The holes in the tray are clearance for 3x10mm screws. The holes in the mounts are sized so screwing in a 3mm screw (metal) will cut threads.

Fabricated using Atomic Filament Gun Metal Gray PLA at 210C, bed at 55C. Wall thickness 2mm all around, 15% infill
