This is a remix of https://www.printables.com/model/253408-customizable-lego-compatible-text-brick-key-fobs

While the original creates a perfectly fitting LEGO brick, the ring to which you attach a keyring lies flat on the print bed. This did not work for my use case, so I created a remix, where the ring is vertical. This allows attaching a keyring and still stacking the keyfob onto a baseplate.

For detailed printing instructions and adjustments of the customizer please take a look at the original model.
