RuntimeError when deselecting object

[Yadunund]

Hi Cole!

Thanks for this excellent tool. I think I might have uncovered an edge case that throws an error.

Steps to reproduce:

1. Import stl mesh
2. Select mesh and click Create->Cylinder.
3. Press X,Y or Z to create the collider
4. Press Esc (error will be thrown)

Thanks for the bug hunting Yadu! I've updated the addon to fix this issue along with some other fixes. Please re-open this issue if the problem still persists for you with the new version but it seems to be fixed in my testing.
