Lathe QCTP DTI (Quick Change Toolpost Dial Test Indicator) Fixture

This is a QCTP DTI (Quick Change Toolpost Dial Test Indicator) holder for an Aloris, or Aloris compatible, fixture / toolholder. It holds a standard round indicator with a 1/4" x 1" lug on the back.

The photo is of a CA toolholder, but I've provided files for AXA, BXA, CXA, and CA QCTP holders.

Specifications for all of the dovetails have an angle of 60 degrees and is as follows:
AXA:
Dovetail Depth - 0.385
Dovetail Width Max - 1.687

BXA:
Dovetail Depth - 0.417
Dovetail Width Max - 1.761

CXA:
Dovetail Depth - 0.555
Dovetail Width Max - 2.201

CA:
Dovetail Depth - 0.49
Dovetail Width Max - 2.66

I've added a small fraction to the dovetail max width, as I found without it that the fit was a little too tight. I've included the Inventor files as well in case you want to modify the model for your QCTP configuration.

Note: Ignore the two tone print... I almost ran out of filament (didn't pay attention to how much was left on the spool prior to starting the print) so swapped filament mid-print to another spool which was a different color.
