Small filament spool carousel

thingiverse

Round and round spins the filament - till it is empty, then it crashes ;-) (special added mechanical warning noise, just build a stack of spools on top and wait^^) printable in less than 1h, uses only one 51104 axial bearing (51104 20 x 35 x 10 mm, not even 2€) fits from 40mm to 60mm inner spool diameter - print it in 0.25 or 0.3 to get "steps" at the outside cone. 51104 snaps in, when not - hot glue! in use since 08/2016
