I wanted a custom keychain for my camper trailer, so I made one. Now you can, too!

I printed these in TPU with the first 2.4mm in white and the last few layers in black. To add a name or phone number to the tag, I used OrcaSlicer's Add Part>Text tool as a modifier with a different filament and a thickness of 0.2mm (1 layer). With this configuration I only had to manually change the filament twice — it prints the name/number first, then the main structure, then the top details.

The model was created in OnShape and you can modify it directly at here.
