Compact Hangboard/Fingerboard/Pinch Block System

So, I wanted a way to train my fingers without committing to drilling holes in my walls or dealing with a massive hangboard. Enter: my 3D printer, way too much free time, and a slightly obsessive need to over-engineer things.

After a bunch of trial and error (and some very questionable early prototypes), I ended up with this—a compact, portable training edge that hangs from adjustable ropes. No screws, no drilling, no commitment. Just throw it over a pull-up bar, rings, a tree branch—whatever you’ve got—and boom, instant finger torture.

What really took time was dialing in the print settings. I spent months tweaking things to get the perfect balance of strength and texture—fuzzy skin for that nice climbing-hold feel, while still being tough enough to handle real training. If you want it even stiffer or stronger, I’d recommend adding extra wall loops rather than relying on more infill.

Oh, and it’s modular! You can adjust the depth with spacers, and if you stack the two halves together, it turns into a pinch block. Feel free to design your own inserts for it. I'm looking forward to see what you come up with. At the moment I'm working on an ergonomic insert. Because why not?

Send me questions on IG @johndecebal as I'm more likely to answer there. Also, I will start posting more of my work there before it makes it here.
