"My solution is to use a couple of pieces of rubber insulation from electrical wire or some heat shrink tubing."
That works up to a point Martin.
It can be very hard to release the part without wiggling it sometimes.
Depending on how much the part stretches the rubber.
I tried it with silicon sleeving (look in the Missusseses iron😊) works a bit better as the silicon gives more on release. Heat shrink is very stiff☹️
I prefer the 'cross over' tweezers (don't forget the Town & Country tires😁) though - instant release👍
