They Might Be Giants Motel Keyring
thingiverse
You must be thinking of some other band. This keyring is inspired by art for They Might Be Giants' 2018 Instant Fan Club; it's inspired in turn by the iconic '80s motel keychain. Designed to either be printed on dual extrusion printers or single extrusion printers when you add a "filament change pause" in your slicer configuration. The lettering is designed to be about .82mm wide, or two extrusion widths on a typical .4mm printer. If you want to modify and regenerate the stl files in OpenSCAD, you need `hershey.scad` from https://www.thingiverse.com/thing:2404566 -- just put it in the same folder with hotel.scad. Because of requiring a "use" file, it doesn't seem to be possible to turn this Thing into a customizer.
With this file you will be able to print They Might Be Giants Motel Keyring with your 3D printer. Click on the button and save the file on your computer to work, edit or customize your design. You can also find more 3D designs for printers on They Might Be Giants Motel Keyring.
