Thanks to Splemsby for the original keychain model. It's a clean model and an easy print, feels good in the hand, just what I was looking for.
Retro hotel keyfob / keychain with a blank face so you can add your own design. You can use 3D modeling software or add a text design directly in PrusaSlicer.
I recommend one of these:
Measurements:
The blank face is 2mm thick, and the ridges on top are an additional 1mm thick (3mm total). So I recommend your embossed design should be around 0.4-0.6mm thick. Enough for a filament color change to show up, but lower than the existing ridges. But hey, be creative, do it however you want.
The author remixed this model.
Removed the embossed graphic using TinkerCAD-- same keychain, just blank.
