My last 3D-printed bracket gits my dial gauge!
It’s a lovely snug fit for mine and there’s no chance of the gauge moving during use, though the channel for the probe is actually not as high as it ideally ought to be.
I’ve corrected that in the design itself now, though I’ve not actually tested this one out. Unless I need to print another I’ll live with the inaccuracy.
I’ll upload the FreeCAD and stl files for these later in case anyone else finds them useful.
