A simple piece to mount a dial test indicator in place of the hotend on a RepRapPro Ormerod.
I got a cheap indicator that didn't have any easy means of bolting it in place, so I made this bit to just have the housing sit snugly in, and that grabs the fixed part of the arm. It is held in place tightly enough by friction that there is no risk of it moving during use.
You need to take off both the hotend and the nozzle mount and attach this in its place. The indicator arm will be in the same position as the hotend nozzle.
It is a parametric design, and should be easy to adapt to DTI's of different dimensions.
