Spoolhoder tube to lower rotational resistance (requires two axle bearings)

thingiverse

In many spool holders, a simple threaded rod is often used to support the spool itself. However, due to its substantial rotational resistance, this can put significant strain on your stepper motors. To address this issue, I designed a tube that can be mounted onto the threaded rod using axle bearings. I selected very standard axle bearings from old inline skates with an outer radius of 11.1 mm and a width of 7 mm. By doing so, the rotational resistance is greatly reduced, thereby protecting your stepper motors from potential damage caused by heavy workloads. The tube itself should fit most common spool sizes and holders, boasting a width of 11.5 cm and a perimeter of 3 cm.
