caliper case

It's very simple to assembly thats why  there is no instructionsMy caliper was standing at my desk without a case and with just it's own sale box (cheap cardboard box with a brand name writen on it)Then I realised that ‘’I have a 3d printer to print at home and a good pc for 3d modelling''. After I realised that I was like ‘’yes baby oh come on I can do this I can get over this'' and modeled a rugged case but my caliper didn't fit inside because when I was  measuring
