Summary

I was heavily influenced by the designs of:
ProgressTH: https://www.thingiverse.com/thing:2449174
skottyorr: https://www.thingiverse.com/thing:1065906 and
eried: https://www.thingiverse.com/thing:15120
but I didn't use anything from their designs.

I tried to simplify the design and this came up.

All design files are on OnShape:
