Thrustmaster T300 T300RS wheel locking collar nub

thingiverse

The collar's correct radius is 35.35mm. For a successful print in PLA, position the curved face upwards on the bed with the flat face facing downwards. You may need to add supports within the hole to ensure the screw inset prints cleanly. To avoid poor edges caused by excessive heat, consider printing two collars at once if you experience difficulty. A 100% infill print typically takes just a few minutes to complete. First, remove the lock screw from the T300 collar. Next, refit the screw through the nub and tighten it firmly in place. Verify that the screw does not protrude into the collar - it shouldn't.
