Bambu Lab A1 Mini Spool Holder

Hallo Community! There are many improved spool holders available for the Bambu Lab A1 Mini. However, none of them satisfied me, so I designed a spool holder with ball bearings that fits into the original mount. I've linked everything you need below. I recommend printing the axle with 100% infill so that it is stable enough for the 1 kg filament spools. You need: 2x Ball bearings: 608 ZZ 8mm x 22mm x 7mm1x Threaded sleeves: brass press-in nuts M4x8x61x screw: countersunk screw M4x12 Boost Me
