A simple 2mm thick keychain tag, with blank face and raised perimeter outline on one side. There is a small hole to attach a keychain. 47mm in length. The exterior is raised 0.2mm if you want to make your font or images flush with the outside. Load it up into an editing program like Tinkercad and customize it. I print these with TPU for flexibility if sat on, and have not tested with other filament yet.
