Airtag Holder: A CAD exercise in precision

Available as a Product on the Downloads page

In mold making, precision is important. Often this means cycling between a test print and design refinement until the right-fitting piece is achieved. These AirTag holders are an excellent exercise in refining a size, the tag either won't snap in, or it won't fit tight enough to stay in, if you don't have exactly the right size. This is where I first came to appreciate how accurate 3D printers can be. Changing the inner diameter a tenth of a millimeter makes the difference between a poor and good fit! Why do these? Because all holders I could find have the keyring hole perpendicular to the tag, this does work if you want to put your keys in your pocket. The few like this have a keyring hole tab that is not big enough to achieve the needed strength. Of course, print this solid, back-side down.

3D Design
3D Design software is used to create dimensionally accurate objects by sketching 2D geometry and transforming it using tools to rotate, extrude, sweep, etc. The software generates the polygon surface.
