Table Top Filament Spool (Mountable)

Drawn up because I couldn't find a good solution for the 5 kg rolls that we sell!

Parts you will need:

2 5/16-18 carriage bolts 6" long (cheapest fastener available)
4 608 bearings
6 5/16-18 nuts
4 5/16 SAE washers too space the bearings away from the printed part
