This is a dial indicator holder designed to fit a Bergström no 0 quick change toolpost and a dial indicator with an 8mm shaft.
It requres two M5 screws, one with a conutersunk head. Just run an M5 tap trough the holes and it's done. Ready to use.
This is for indicating on the external diameter of a workpiece. Just use the mirror function in your favorite slicer to make an indicator holder for the workpiece face.
Print this thing in the orientation it will be used. No need for support. 100% infill makes it nice and solid.
No STL preview, dont know why?!
