Miniature Priming Handle Basing Handle

Update (last two pics): I made a version 2.5 after using the handle for some minis. I made the following changes:
The rubber bands were kinds too close so i made the gaps a bit wider (the new version needs "arm" printed 8 times, see also below for options).
I added a hole for the top washer (M5,5x15).
Moved the rotating arm a bit to the front (previously it was in the middle to help the priming handle stand upright). I added a groove at the bottom for another "rubber band arm" so that it can stand once more (you need to print "arm" nine times if you want this feature)
Still torn on the diameter of the screw hole, let me know what you prefer!

I used a M5x40mm Screw, four Washers and three nuts to secure the handle to the rotating part (see assembly below). And some flat rubber bands inbetween the Arms (0,5cm thick and approx 6cm long when layed flat but that shouldnt matter too much)

The Arms snap in pl
