6m or 1/4 CNC Tramming tool holder

This is a tram tool holder, which I designed while tuning my Milo 1.5.

It uses one M3 heat insert to hold the tools in place. If you use the arm, you’ll need an additional M5 heat insert.

I recommend using tree supports, although they’re not strictly necessary.

The stiffer the material, the better, as it reduces deflection.

Warning: The tolerances are pretty tight, so make sure your printer is well-tuned using something like a calibration cauliflower. Use at your own risk. 

PLEASE TEST and tighten everything before leaving a 200$+ tool in the holder.
