Thank you! I'm glad you like it! Please let me know if you have any feedback or hit bugs.
I've found printy works best if you prompt her like:
1. Situational context (eg: my kids pull the toilet paper and it free spins till the roll is empty)
2. Specifics (eg: my roll holder is 9mm in diameter and 10cm long)
3. Desired outcome (eg: I want something I can clip on it to add friction and slow the roll down from spinning)
Wait, can you share the STL for that, via the site?
