Please watch this video for more information: https://youtu.be/bnpQIUH3ix4 This is a really simple Pokéball I created with tabs on the back so it can be easily hung on things. Can be used as a keychain or necklace, etc. It's just one file and it'll print really easily. The parts should pressure fit together. I printed it on my Robo 3D using PLA at 0.1mm layer height with 10% infill. No supports or rafts needed. Then for color I just used a red and black sharpie I had at my desk. :) Hope you enjoy!
