The file 'Inside/Outside Lid Calipers (12 Inch) 3D Printer Model' is (scad,stl,txt) file type, size is 15.3KB.
Lid Calipers for Ceramics. Maximum Diameter 12", just barely fit on my 3d printer.
See: https://www.youtube.com/watch?v=wAIOai4c9S4 for how to use.
Note: With ABS, I've experienced some problems with warping. You may want to use PLA. Regardless, if you do experience warping, put the pieces together curving inwards to minimize the error.
Sized for M6 hardware. You'll need a short bolt and a wing nut. I'm using a standard nut in the photos, but it's too difficult to hand-tighten.
