He probably made them himself. This part is so small I don't think the
weight will make a difference to the motor bearings. If nobody else has
time I could make some.

Will you be having more produced? Depending on the cost I would like to
have 10 or 20.
If you aren't about to order some, can you release the manufacturer of the
Delrin collet to sell some to a third party?
I would place the group order myself.
Although I collaborated with Tom Jobe for the design of the Brass collet
that led to the 2D in the files section,
I never liked the fact the initial samples were made of brass. Brass made
the impeller much heavier than it needed to be
putting unnecessary stress on the motor bearings.
