When my landlord gave me permission to change all the locks on my rental home, I made a key fob with my street address to put on the key I sent to her. The picture shown is a sample.

The point of this is for you to customize your own. There's no reason to print the sample 3mf file unless you really want a key fob that says "888 Royal Suite".

In the OpenSCAD Customizer pane, you can specify up to 5 lines of text, change the font, font size, margin around the text, and so on.

This requires one of the daily snapshot builds of OpenSCAD due to its dependence on the roof() operation to make beveled edges on a polygon with an irregular perimeter.

Print settings

Supports: No

Resolution: 0.20 mm layer height, 0.4 mm nozzle

Infill: 25% cubic

Notes:

You don't need a MMU or AMS to print multi-color. You can set your slicer to pause for a color change at the layer where the bottom text gets covered, and then change back to the original color at the layer where the top text starts to appear. This gives you engraved text with a different color background.

How I designed this

This is a fairly simple design done in OpenSCAD, as a reason to experiment with the roof() operation that's available in the daily snapshot versions (after 2021.01). It's a way to bevel an extrusion of an irregular polygon with concavities. Just apply roof() to the polygon and subtract a cube() off the top, and you have a beveled polygon cap that you can put on top of a straight extrusion of the same polygon.
