Porta rullo filamento Alfawise U20

thingiverse

Realized for use with the skate bearings, a 7mm hole (model 627). It is attached above the external unit, power supply and screen of the printer. In both sides I have inserted a 1 millimeter spacer in contact with the inner cylinder of the bearing. The upper opening is 9 mm (7 mm of bearing 627 + 2 mm of spacers). I recommend a wall thickness of 4 lines to give more solidity to the fittings of the structure. The fittings are hard to assemble, but the assembled piece results very solid and resistant.
