Theragun Mini Handle Adapter

When my dominant hand got sprained in a fall, I couldn't reach my shoulders and back with the Theragun Mini.  I created this adapter that accepts any paint brush, broom or squeegee handle that has a 3/4" 5 TPI ACME threaded tip.

I had to seal the holes due to warp snagging during printing so you'll have to cut the vent, button and indicator light holes manually.
Most of the prototype printed in thin walled PLA stood up.  But the PLA latch snapped after a couple days.  The PETG version of latch is holding fine so far.

3rd revision is provided for download and incorporates a more simple handle receiver, reinforced lower halves and slightly revised latch area.
