Paintbrush Keychain with hidden image inside

This is a paintbrush keychain for those who like painting. It has a hidden slot inside to add your own photo but may need a few pages as mine was laminated. Printed at an angle for more strength and the photo slot is meant to represent a colored paint. The first print was with pla but it is quite weak as is photo frame is fragile. I reprinted with petg and it is quite stable and hasn't broken yet. Feel free to follow me on instagram @ Cosmin_Design_ . I am new to designing for 3d printing and am open to questions
