This is a simple mount allowing you to mount the POTA33H carbon fiber mast to a square hitch bar.

The bar that I use is from the Harbor Freight bed bed extender. It is approximately 50mm square, and the opening in the print is 50.6mm

There are holes on the side of the square mount to secure the mount to the hitch mount with a screw (or eye bolt)

I printed this in PETG at 100% for strength, and I also use the top 11 sections of a regular pota33 to replace the top 6 sections of the pota33h to get a 44' mast total
