AirTag Keychain Holder w HueForge Portrait

Simple AirTag keychain holder when printing one of each side.  There are cutouts to make it easier to open the holder when closed and indicators on the side for how to line up the sides together.

The version with the HueForge cutout is designed to take a 34.6x1.4mm circular HueForge portrait, which should provide a good number of layers to work with when using either a .4 or .2mm nozzle.  When printing the side with the cutout support material is required.  Using a 40% first layer density (available setting in OrcaSlicer) and a .42 mm top interface spacing should make for easily removable support material.

Adds a cutout for a 34.6x1.4mm circular HueForge portrait.
