AirTag Wallet Card

Keep your AirTag in place in your wallet by popping it into this card-shaped adapter, ensuring that it doesn't slide around and fall out!

The circular part of this card is based on the top half of the AirTag Case Keyring holder by _gimpelginster, but the rest of the card is really just a simple rectangle. When you combine that with a hexagon infill and 0 top or bottom solid layers, you get a lightweight-but-sturdy card that also looks kinda neat, saves on print time, and reduces plastic waste!

The thickness of the card itself is equivalent to 4 credit cards stacked, but the AirTag stands taller than the card. This is simply meant to give your AirTag some support in your wallet if you've got some extra space that's not being used by other cards.

Print Instructions
I've provided gcode for the infill at 8% (black photo) and 15% (grey photo), as both have been tested and work great! Both sizes were printed with 0.3mm and 0.2mm layer height and 3 perimeters.

The 3MF is also available, with the proper print settings applied, but you might notice that the scale is set to 9.75%. This was done on purpose, as the export from Fusion had the STL at gargantuan sizes. If the fit doesn't work for you on your printer, nudge the scale by ±0.05%, otherwise you might overshoot.

If you'd rather roll your own with the STL, it's been sized appropriately, since I exported from PrusaSlicer once I got everything dialed in. In order to get the infill effect, just head over to Print Settings → Layers and perimeters → Horizontal shells, and set the “Top” and “Bottom” values each to 0. Then you can change the infill pattern and densities to your liking!

Assembly

• Press the white side of the AirTag into the center hole with a semi-scooping motion. The fit is tight, so pressing it in requires a bit of force, but if it just won't go in, try approaching from the other side of the card before resorting to a re-print. I've found one side to be just a bit easier than the other when pressing into place.

If you'd like the STEP or Fusion360 files, just shoot me a message. I've just not posted them here because of how janky the workspaces are, but I'm happy to provide upon request!
