3D model description

Are you getting Apple's new AirTags? Not too excited to pay $12-$30 dollars or more for a case? Neither was I, so I designed this sleek twist-lock case with a keyring loop to hold an AirTag.

Attach it to your keyring, backpack, luggage, or any other item you want to keep track of. This has been designed based upon Apple's published design specs of 31.9mm x 8mm with it's unique curved profile shape.

4-29-2021 - STL now updated to V2, improved fit for AirTag

3D printing settings

0.1mm or 0.15mm layer height, with supports. PETG or PLA. Depending on your printer, you may need to scale this to 101% size in your slicer and reprint if it does not fit the first time.

A little about my 3D printing cred. My first 3D printer was an M3D Micro in 2015, I then backed (and received) a Tiko 3D, both were Kickstarter projects. My next acquisition was a refurbished Wanhao Duplicator i3 Plus, then a new at the time Creality CR-10 that has been extremely modded (its now a dual Z, dual filament CR-10S, 32bit controller, and more). My next addition was a Creality Ender 3 which is now also extremely modded, then followed the Monoprice i3 Mini (Wanhao) it was too cheap to pass up, and more recently two Prusa MK3S and two resin printers, the Elegoo Mars and the Beam3D Prism (also a Kickstarter). I now have 14 3D printers... I think I have a problem ;)

I have been designing 3D printer parts for the past five years, and since the fall of 2018 I am the current designer and curator of the Hero Me series of parts and hot-end cooling systems for Creality 3D printers (and clones). I recently released the Hero Me Gen5 Master Suite 3D printer cooling system available here:

I like the idea and appreciate your effort. Unfortunatley, I am not going to use the print for daily use. The lock mechanism with the thin bridges can break easily and the design is not great for FDM printing. Hard to find a good orientation, small surface on the printbed, many overhangs. For me, the result is not very clean, even with supports for the handle. I use PETG for better temperature stability (e.g. in a car).
For now I am going to use a simple one part design (Thingiverse thing:4845981), but maybe you are able to improve your design for better printing quality.

Yes, thanks. That is exactly what I wrote in the printer hints: "Depending on your printer, you may need to scale this to 101% size in your slicer and reprint if it does not fit the first time." Different filaments have differing 'shrink properties. The 100% printing works for me. Your results obviously varied from mine. I did not want to make it larger that would have the AirTag float loose in the case.

The design is nice, but it doesn’t fit as-is. Needs to be scaled up a little bit to fit properly.
