This is a replacement gear for the Dyson V6 motorized brush head. There was a number on my original gear: “T103310 2B”. I do not know if that is a model number or not.
It goes inside the motor assembly and connects the motor to the brush via a toothed belt.
This part is under significant stress, friction and heat when the brush seizes but the motor continues to run.
It should be printed in the toughest material you have available.
PA-CF is ideal.
PLA or PLA+ will most likely immediately melt or break.
The author marked this model as their own original creation.
