Since I wanted to have the oppertunity to change the colors of the hands of the famous Hollow Clock 4 I made some covers for both hands and also i made a hour hand that extends 0.5 mm in the middle to make room for the cover to pass the minute hand.

The hour hand has a larger gap for the magnets so it won't drop due to the extra 'weight'. The magnets I used are 8x2. But in the end they were 8x1.7 so i made a gap for 2 magnets which you don't have to glue.
