Build on the platform.
We built the universal hardware platform. You build whatever you want on top of it. The dock, the magnets, and the metal inserts are solved problems — your grip design is the only thing left to invent.
Buy the Hardware
Sourcing exact-thickness magnets, die-cut 3M tape, and matched metal inserts one-off is a nightmare — wrong tolerance and your print wobbles or won't seat. The Maker Kit skips it: dock, metal inserts, tape, and the QR card to the CAD files, all pre-matched.
Get the CAD Files
Every kit ships a secure QR code straight to the .STEP files for the blank grip cap. Pull it into Fusion 360, model your own topography on top of the pre-solved mounting geometry, and print.
Files are CC BY-NC — personal use only.
Tolerance note
The mounting geometry is held to a 0.2 mm tolerance. Expect roughly 1–2% scale drift between printers depending on calibration — check fit against the dock before you commit to a full print run.
Design it. Win it. Get paid.
