Trục lăn trung tâm cho hộp sấy filament từ hũ đựng ngũ cốc

This is a center axle bracket that uses the existing bearing holder and axle.

I added two different diameter axels to use for spools with larger or smaller center holes.

Print Axels with supports as they are at a 30-degree angle to make them stronger

Modified the bearing holder to be a saddle,

added bearing holders at different heights to adjust for different inner diameter spools and added a small lip on the inside to help hold the axle in place
