This is a universal replacement wheel magnet housing for cycle computers. Clamps across two spokes for a secure fit.
This design fits a standard 12mm x [1, 2, or 3mm] circular magnet, easily found at hobby / electronics stores, online, or (conveniently) in a lot of magnetically-affixed IKEA smart switches.
Designed with straight 2mm (14ga) spokes in mind, but should also fit butted spokes down to 1.8mm (15ga) and up to ~2.6mm (12ga). Tested with 32H and 36H cross-laced wheelsets - because this clamps across 2 spokes, you may have issues if your wheel is radially laced.
You will need 2 identical prints to form the clamshell housing.
