Crimpdeq Grips

Crimpdeq Grips are 3D-printed grips for isolated finger training: each finger rests on its own roller, under a block that holds its last joint. There are two designs, both parametric OpenSCAD models:

• Photon, fitted to your hand: measure a photo of it and download parts that place every roller under its fingertip.
• Spark, with larger rollers (22 to 40 mm). Its chapters are still to come; the same measuring page downloads its parts, with the rollers placed from your photo or at their defaults, and they go together in the same order (see Assembly).

Every part, pins included, prints in the same plastic: no metal rods, screws or TPU. The only extra is a cord through the anchor.

Getting the parts

Each release attaches the STLs of both grips for both hands, at the models’ defaults, and a Bambu Studio project of each for the Bambu Lab A1; Photon defaults to one measured right hand. To fit the grips to your own hand, download the parts from the measuring page.

Credits

The grips build on OpenGrips and on Jared-Is-Coding’s fork, whose Prometheus v43 and Sisyphus v27 STEP files the OpenSCAD models rebuild as Photon and Spark. Like them, this project is released under CC0.

All illustrations are rendered from the OpenSCAD models, so they match the exported parts.
