Airpod Holder for Keychain

thingiverse

The Apple Airpod case has no way to attach it to a keychain, and no way to attach a small light or other accessory. I saw a design on Thingiverse here: https://www.thingiverse.com/thing:2169936 but it was too thick, and the hole seemed way too large, making the small Airpod case very bulky. I realized that the part actually only needs to be a little more than 1mm thick, so I made my own part. I have included two versions, one that is 7mm high and the other 14mm high. I chose these heights because they are just slightly taller than 1/4" and 1/2" respectively, and you can then use the Brother P-Touch labeler (or similar label device) to put a label on top of the part. If you look carefully at the picture of the part installed on the Airpod, you'll see a Brother white label. I airbrushed out the text, since the label had the phone number and email of the person from whom I designed this part. The part that you see in the picture is my original prototype that was the same thickness as the part I linked to above. However, the part in the attached STL files is only 1.1 mm thick, which is about 1/3 the thickness of the other person's design. The person who designed the original part recommended installing this from the bottom in order to avoid any pressure on the hinge, if you were to install from the top. I think that is a good idea. I designed the part in Fusion 360. It is a parameter-driven design, so you can simply change the height or thickness in the parameters without having to edit the design. Certain design changes may require you to manually alter the fillet parameters but you can, if you wish, ignore the fillet error messages, if you get them, and print the part without the fillets.
