Multifix AA Dial Indicator Holder

The holder is available in a version for radial and one for axial runout measurement.

You can also use one for both directions if you add 2 heat set inserts for the height adjuster on the “bottom-site”. It just doesn't look that pretty on the underside and you need to switch the height adjuster to the correct site every time you switch from axial to radial and vice-versa. 

The height adjuster is available in one version for a heat set insert for the height adjuster  screws and one with a 2.5mm hole for tapping. I partially tapped here and by that got enough friction on the screw so that no counter nut is needed to hold the screw in the right height position.

Printing is up-side-down, all parts are in print orientation in the stl files.

You need three or four M3 x H 5 x D 4.2 heat set inserts, three M3 x 18 and one M3 x 28 screws (complete length including head, shaft and thread).
