Hey,
thank you for the review! I did not test the Addon in Blender 4.5, I should change the Compatibility asap.
If you continue to run into Py errors, feel free to create an issue on github and give me some details about the issue (error messages or the things you did leading up to the crash).
Regarding the scaling issues, I just played around in Blender 4.5 and could not replicate the problem. Here are two things to look out for:
I hope this comment was helpful :)
I'm getting a lot of Py errors on blender 4.5 doesn't work if the 3d model is at the scale you will be printing it (10cm). it's too small. you have to scale up your model (x10) and then scale down to print. That's a lot of hassle. It has a lot of potential, but it's too buggy right now :(
