Filament Spool Holder - 100mm/52mm/32mm - 8mm bore

I have an assortment of filament spools with three hub diameters, 100mm, 52mm, and 32mm. This is to cater for those three sizes, and will (read 'should') fit on an 8mm thread rod.

The outer section is 120mm, the 100mm section is actually 99mm for some clearance, the 52mm is 51mm and the 32mm is 31mm.

I printed this in PLA at 195C and 45C on the heat bed.
