Update: Added new version of knop with slightly bigger hole to improve fit.
Prints perfect on Ultimaker with 25mm/s print speed and additional cooling during the last, smallest part.
Printed the parts using PLA with a layer height of 0.2mm.
The holes in this design are the tricky part, you’ll most likely have to redrill them after printing. If you can’t print it with the hole in the smaller cylinder, use the provided _nohole version.
For assembly simply put a 2mm rod through the handle and the main part, this rod will act as hinge for the handle.
Remove the small 2mm rod from your old Hasselblad battery-door-screw and you should be able to remove the screw from the battery-door. Then just insert the new screw and put the rod back in place.
