Prusa MK3 snapon filament sample holder

A simple snapon mini spool holder for the extruder motor of the Prusa MK3 printer.

Print all elementes in PLA with 0.2mm layer, increase to 0.1 for the thread of the holder.

The holder needs support, the thread needs a little rework for the cap to work smoothly

Use some grease for the thread of the spool. 

There are holes in the spool for fixation of the filament…
