Monoprice MP i3 Mini (Wanhao, Cocoon, PowerSpec) filament spindle

Model originally uploaded to Thingiverse at https://www.thingiverse.com/thing:3212255.

I wanted to save some filament and time to print, so I hollowed out the filament holder but kept the strength to carry the weight of a full roll.

Print with 3 walls and 5 top and bottom layers.
