Conveyor roll

I corrected the 4 missing rolls right away. The details are as follows: 0.1mm layer height, ABS material, 100% infill density, and smoothed with acetone for a sleek finish. Additionally, M6 rods fit perfectly. This design prints neatly within a 200mm diameter area. If that's not feasible, simply print two rollers separately and combine them to create one long roller.
