Customizable Heavy Duty Luggage Tag!
by fehknt, published
This luggage tag is designed to fit a standard business card, but maybe your business is non-standard! So of course you can customize it to fit whatever type of card you want. It's a 2 piece print that bolts together at the corners and the pressure clamps the card in. And just for fun it has an open-source hardware logo cutout in the back.

The default values provided will fit a standard business card and M3x10 screws. Most configurable parameters are enabled for the customizer, or download the SCAD and mess with it as much as you want. The (short) OSHW logo file is pasted directly in so that it's totally standalone. There is a surprising amount of variation in business cards though, so be sure to measure yours and customize! (Recommended ~.1mm extra in case of printer slop, dependent on your printer...)
The base has a 1 layer_height layer to act as a bridge to hold up the narrowing of the hex head to the bolt shaft diameter. I would have just printed it the other side down, except a small indent for the card is a good idea.
If you want to waterproof it, just put some plastic wrap under and over, then bolt it down so you get a nice plastic-on-plastic "smush" seal, or, if a more robust solution is desired, laminate your card before insertion. If lamination makes it too thick or too big or both, well, that's why it's customizable. You probably only have to reprint the base if that's the case. Also you can just print the solid base and tape a business card on with packing tape or the like, see the second one I made that is nice and thin to be used that way.
The height is specifically pretty thick for two reasons: (1) so it doesn't break, and (2) so the screws don't protrude at all. But feel free to make it so that it does protrude, I didn't explicitly force the bolt length to be 'correct' in any way.
Basically, either print the plate() as-is, or call top() and bottom() to print that instead.
My printed copy is without logo because I added that while it was printing, but it should not affect anything, except for taking less plastic to print.
