Retractable Brush

This was inspired by https://makerworld.com/en/models/1142299-retractable-hairbrush-v2?from=search#profileId-1174842I was having some trouble with assembly so decided to design my own. Only 8mm thick! No supports needed. No glue needed, snap on back case which is nice and flat allowing for adding your own design to spruce it up, see the heart design I experimented with. “Locking” mechanism when extending prongs uses compliant mechanism. Please see video below for assembly instructions. Please note the prongs have a “flat end” which, if you look at the video, should be facing to the left.
