New Rice Bucket Filament Holder

Next-generation filament dry box holder. This holder has undergone integrated optimization compared to the previous design, integrating the temperature and humidity fixing position onto the main body of the holder, and also featuring aesthetic enhancements and reinforcement for the main body. The roller part has also seen significant changes, with bearings integrated into the rollers, making them easier to replace and to insert into the snap-fit positions on the main body. Unlike the first version, there is no need to adjust bearing positions for a perfect fit, and the filament pull-out smoothness is also improved. Overall, only one hardware component is required, which is the bearing. The bearing model is 92900zz 10*22*7. Note: when printing, it is best to use 100% infill for the crossbar. The crossbar comes in two types, A and B, with an outer diameter difference of about 0.02, where A is slightly smaller. If the printed part is loose, choose the B type crossbar
