Airtag holder for bike fork

We designed a holder to attach an Apple Airtag to a bicycle, under the fork.

The design is made of three parts:

• Insert: fits the inner diameter of the fork tube and holds everything in place.
• Body: joins the Insert and the Cover in place
• Cover: closes the assembly, holding the Airtag

Additionally, you'll need a 6 mm screw, longer than the diameter of the lower part of the fork, and an M6 hex nylock nut.

Printing

We printed ours at 0.12 mm layer height, using a 0.4 mm nozzle.

The parts must be printed in the provided orientation, and only the Insert requires support material. 

Use at least 3 perimeters in your slicer software.

We used PLA for testing, and it has worked perfectly for months (still working), but for better resistance to the sunlight or other elements we recommend using ASA or PETG.

Assembly

1. Slide the Insert through the Body. 
2. Place the Airtag in the body and close the Body and Cover toghether (tight snap fit).
3. Slide the assembly into the lower side of the fork opening.
4. Secure with a screw and hex nyloc nut.

Use the following image for reference.

Compatibility

This model was made to fit Decathlon's Riverside 120, but it may work for other bicycles too. The key dimensions are the diameters of the opening under the fork. In this case, the outer diameter is 35 mm and the inner diameter is greater than 22 mm.

We are providing the STEP files so you can check the dimensions and make adjustments if needed.

Disclaimer

Due to the different properties of 3D printing filaments and the tolerances of different machines, you might need to scale up or down some of the print files, in case they don't fit when you print them. 

The Airtag is held in place through a snap fit between two 3D printed plastic components. We have tested the reliability of the joint for months, but we still cannot guarantee that it will work reliably for your print settings and filament. We have not tested this design on heavy trails. Adjust the parts at your discretion and use common sense before using it for intense rides.
