Measuring stick HampusPinnen QuickStick

My car mechanic friend had this idea for a 3d printed tool he could use at work to make measuring brake discs on vehicles a bit easier while still having tires on.

After discussing specifications for a while and trying some different design I came up with this. You print two of each and then just assemble them, my first 3d creation and improvements can of course be made, but feedback from my friend is that they use it and seems to work as intended.
