Trallalla filament spool

thingiverse

Human: Trallalla is a support system with conical centering plugs for spools with passage holes ranging from 46 mm to 65 mm. I've always used a bobbin support system positioned above my printer, but lately, with the generous dimensions of some spools, I had to think about a different system since vibrations during unwinding caused print results with some defects. Print Settings Printer Brand: RepRap Printer: Prusa i3 Custom Rafts: No Supports: No Resolution: 0.3 Infill: 5% Notes: Since low infill usage is recommended, it's suggested to apply at least 4 upper and lower layers to avoid a mottled finish, like the one I obtained. Custom Section Materials Needed: Print files STL of project design 2 ball bearings model: 608Z 3 threaded rods length 151 mm diameter 8 mm 14 M8 screws 14 M8 nuts
