mesh-tumbler's Issues

IndexError: index 3 is out of bounds for axis 0 with size 3

Tried with the Grafana mascot grot stl that you can get from here https://www.printables.com/model/655662-grafana-grot-mascot/files

I tried with other STL and it seems to be able to process it but it failed with that one.

ModuleNotFoundError: No module named 'tqdm'

I ran pip install . (using asdf for a local python install) and got ModuleNotFoundError: No module named 'tqdm' when trying to run the tool.

After pip install tqdm it worked (for only specific stls)

"pipx install"ed version fails

$ pipx install .

I did not file a PR to depend on tqdm in part because tqdm is only used inside an unused function. However, with this modification, the pipx-installed version did run:
