These new wheels for the original Prusa Lack Enclosure Spool Holder consist of 608 ball bearings (22 mm x 7 mm). Unlike other solutions here the filament spool rolls directly on the metal bearing surface minimizing noise, friction and resistance.
Also suited for most larger spools up to 5 kg with max. rim width of 7 mm.
These wheels are a drop-in replacement for the original wheels. Mount with a M4x20 screw to fix the axle. The discs provide a small separator rim which must face towards the ball bearing.
The unmodified base for the holder is also included here for completeness.
