Edge Lift Designer

What is Edge Lift Designer?

Edge Lift Designer makes a 3D printable lift block for climbing training (edge lifts or block pulls) with an unlevel edge. Each finger's edge height follows the length of that finger's first segment, from knuckle to middle joint, so the shorter fingers meet the edge in the same position as the longer ones. The plate follows the familiar lift-block layout: a rounded frame with a pocket, printed pocket up, with cord holes in the side bars.

You can type your hand measurements in or take them from a photo with a ruler in it. Detect hand places the knuckles and joints for you (MediaPipe, running on your device), and you drag them into place. One hand gives one stepped edge, both hands give a stepped edge each. You set the edge depth, front radius, pocket size, frame and cord hole shape, and a strength check shows a safety factor for your heaviest pull and material strength. Export is an STL, or a 3MF for PrusaSlicer, OrcaSlicer or Bambu Studio that carries layer height, walls, infill and optional denser-infill zones.

It is free, needs no account and runs in your browser; measurements and photos stay on your device. The code is open source under the MIT license on GitHub. The README notes that evidence for unlevel edges is still thin, and that you print and train at your own risk.

What you can make

• Edge lift blocks for finger training
• Unlevel edges fitted to your hand
• Two-hand lift plates

How to use Edge Lift Designer

1. Measure your fingers by hand or from a photo with a ruler
2. Set the edge depth, front radius and pocket size
3. Check the safety factor at your heaviest pull
4. Export STL or 3MF and print it flat, pocket up, without supports
