Worx PowerShare Battery Mount

This is a remix of [Worx 20v and 40v Battery Holders](https://www.thingiverse.com/thing:4092648), which was incomplete and has not been updated in a year. The previous design did not allow the battery to seat fully. I have modified the design and now the battery clips in properly. It should work with both 20V and 40V Worx PowerShare batteries, including the "Pro" versions.

This is not fussy about resolution - I printed in .30 "Draft" mode, with 20% infill, and it came out great. Lay it flat on the build plate and enable supports "everywhere", to support the side rails.

6/16/2021 - Please note that this design fits Worx Powershare batteries sold in the US. Those sold in the UK and EU seem to have a different, incompatible design.
