The original sits on a table. This one is built to travel: small enough to clip to your gear, and simple enough to print at home.
It was designed for 3D printing from the start. Three parts print flat with no supports, and a durable snap-fit holds them together through repeated pulls, with no screws and no glue.

How it plays
Each player hooks one finger into an opposing inner track and pulls the other way. It's a miniature tug-of-war that tests crimp strength head to head.
The open space inside the outer frame doubles as a structural loop. It takes a standard carabiner, so the trainer clips straight onto a backpack or chalk bag and goes wherever your gear goes.
Sketch to shape
Ideation sketches explored the frame and the inner track, and how the outer loop could double as a carabiner clip. An earlier tray-style trainer came first, before the idea narrowed down to a single finger.
Made to print
Every part sits flat on the print bed, so the geometry needs no supports and comes off the printer ready to assemble. The frame and the inner track snap together, and the joint keeps the strength needed for repeated use.
That makes it easy to share: anyone with a desktop printer can make one.
Twelve gym colorways
I rendered twelve colorways in Blender, each named after a climbing gym in Manila. Pick a swatch to swap the colorway.
