This is a dial indicator holder for Snapmaker 3-in-1 machines.

Fits standard dial indicators with a rear mounting bracket.

The holes in the holder are designed for ruthex M4 heatset inserts (5 pieces D5.6 L8.1) - however, heatset inserts from other manufacturers with a similar diameter should also fit. 

Five M4 cylinder head screws (L approx. 15-20 mm) are required for attachment if the bracing plate is attached to the toolhead slider. 

The holder should also be usable with correspondingly shorter screws without the bracing plate installed - but I haven't tested this. 

Furthermore, the holder can of course also be mounted without heatset inserts using the appropriate screws, nuts, and washers.
