This keychain is designed to be stylish, easy to print, and easy to customize. A keyring easily fits through the hexagon on the left side of the model. Use your slicer or modeling software to add lettering on the flat side (not the side that has hexagons over the center oval). This model works well with AMS/MMU systems as shown in my example picture. Lettering too small may not print well. Keep in mind that the whole object is only 63.5mm wide (2.5 inches) so if you have a lot of lettering to put on it, you may want to scale it up first.
