I am sure no one is interested but this failure is common to Dremels. It is called a flexible coupler (known at Ace Hardware as 3/8" plastic tubing) and you can order it from Dremel. (It simply connects the motor to the collet.) However I went down to Ace and got about two inches of the tubing for free.

Used the heat gun to soften it and put a piece about half an inch long to connect the main motor and the collet.

Bingo; works like a charm. Now I just need a project where I need to use it.

One pic shows the tubing and the other shows it repaired - but I do not think you can see the new flexible coupler.

File this under "Too much time on my hands."
