I created this key chain for multiple keys, which I don't need all the time, like for two cars, It's getting to big, an multiple loose key chains aren't the solution for me either.
You can put a 20mm width strip of Velcro to the front and back of the keypads. and if your Velcro is a bit wider, change scale accordingly for all parts.
Printed it with PETG, but PLA would work fine to. Both files attached.
Did not put the text in the model, so you can add your own text with Prusa slicer settings.
Cut the Velcro with a sharp knife to fit the key pads and base pad nicely.
Finally, this print is a really small one, total time to print for 4 keys and base holder is 62min.
Change the embossed text to your likings and make your key chain personal!
