Broom Handle Connector for Broom with rubber bristles.

My broom head with rubber bristles broke off from the handle and I could not find an adapter that fitted anywhere else, so I decided to design one myself.
The brushes part seemed to be tapered inside, so I have tapered the end slightly.
It fits both inside and outside of the handle, so it is quite strong. This also makes it easier to print without supports.
I did not use any glue.
You may want to put some oil on the metal handle before inserting it into the adapter, to make it easier to push on.

Measurements:
Overall 40mm long. 22mm wide
Handle part 22mm diameter; internal cylinder 19mm diameter, 1mm gap.
Thread part 20mm diameter; 20mm long

The thread was created in Autodesk Fusion and then stretched to get the right number and thickness of turns.
