The story so far
It started at a ping pong table.
-
Ping pong balls kept rolling away
The first version was a small holder glued to a ping pong paddle, built to stop balls from blowing off the table.
-
From the table to the court
The clamp idea turned out to fit wheelchair rails. After learning about adaptive sports through the Challenged Athletes Foundation, the project shifted to wheelchair pickleball.
-
First 3D printed docks
A ball cage on a screw-on clamp. It held, but it was hard to put on and take off, and tough to print cleanly.
-
Version 2: rebuilt to print without supports
The cup now sits flat on the printer bed, with thicker fingers and a slide-on dovetail in place of the screw.
-
Version 6: a cleaner clamp
After v2 the clamp went through a few more rounds. v6 keeps the proven v2 cup and adds a taller clamp with a round face that matches the cup.
-
Tested with athletes
Fit and strength both passed at the October 2026 session in San Diego. Placement is the next thing to work on.
