First of all, no selling of this model is allowed, since I am already selling it on Etsy.
I printed mine with .12 layer height on an Ender 3 V2.
None of the parts were printed with supports except the bottom dome piece.
The middle piece and bottom piece as well as the button and the ring piece should be able to snap together, but if it is a little loose you can use some super glue. Then just glue the button to the middle piece. The blank key rings I used were from amazon.ca.
I would love feedback from you guys in the comments, and I will do my best to answer all questions. Hope you enjoy.
If you want to give me a tip, I would appreciate it. Paypal
