PM 728 VT Spindle Lock

This is a spindle lock for the Precision Matthews PM 728 VT Mill.
Removes the need to have 3 hands and the annoying C wrench.

First use the top to rotate the spindle so that’s it straight.
Then turn it over and place it on the spindle cap flats. Push it all the way down.
Use an 11mm wrench to loosen or tighten the draw bar. Keep a hand on your tool/collet so it doesn't fall out.
The print will flex when you have tightened it enough. Happy accident but it’s a good gauge to not over-tightening the draw bar.

Print the top down on the bed with 6 walls and 4 top and bottom shells. 15% Gyroid infill.
PETG or similar filament that has some resistance to oil.
