I thought this was a fun model, but unfortunately it had a block in the way which made it unusable. I fixed it!
While I was in a hurry, I didn't have time to optimize the model, so it is super high detail and longer print time.
I'm HOPEFUL that I will find time to update it, but until now it at least will work. 🤞
Best with a ball bearing or a marble inside to keep it rolling around and weighted properly.
Have fun friends!
The author remixed this model.
I added the screw and bottom as STL files as requested.
