Filawinder PTFE stopper
thingiverse
As a Filawinder user, you may have noticed that imperfectly straight filament can cause serious issues when it passes through the PTFE tube. Specifically, it tends to drag the tube towards the spool, putting excessive stress on the servo and potentially causing a break. This is because the tube diameter exceeds the dimensions of the servo arm slot. To mitigate this problem, a simple accessory can be attached securely to the Filawinder's base. By blocking the PTFE while allowing filament passage to the spool, this addition effectively prevents tube displacement. However, if the produced filament is severely twisted and curled, you may still risk damaging the motor.
