Filament Spool Adapters with Skate Bearing

thingiverse

Here are the adapters for your filament spools. A standard skateboard bearing fits into these adapters, allowing them to roll smoothly and evenly without putting strain on the filament while printing. These arms are specifically designed for the Prusa I3 printer. The bearing used is a standard skate bearing, 7mm deep, 22mm wide and 8mm in diameter. To assemble the spool adapter, you will need an 8mm shaft screwdriver to support the spool between the arms. The sizes of these adapters are included: 32mm, 50mm, 51.5mm and 54.5mm. There is also a universal spool adapter that can fit various filament spool sizes. **Print Settings** Printer Brand: RepRap Printer: Prusa I3 MK2 Rafts: No Supports: Doesn't Matter Notes: I print them in ABS, but they work great with PLA.
