卡尺支架（2种型号的卡尺）

I wanted to hold my caliper on side of the power supply to do not damage it but to easily access it
I also made a fit veion with a "hook" for my ruler but realized that i should not have put it on side but on the "bottom" part so I end up doing a third veion
I put the 3 veion to let you go with your mood
