Dog Tag Bone Trim Ring for Collar

Made this for my dogs noisy metal name tag on their collars. Bone shape which is popular from online retailers.

Instructions:

The ring is best made from TPU or similar.
Blank from PLA or similar.

1. Print blank
2. Start trim ring print and stop just before overhang layer begins
3. Insert blank into object cavity
4. Finish print
5. Remove blank
6. Enjoy

Details:
First tried printing with supports, which made for a messy print on the upper layers due to the overhang. Overcame it
