About this 3D model

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.
