Modular Hangboard for Climbing Finger Strength Training

This is a modular hangboard system for training finger strength and finger health for rock climbing and bouldering.

This modular hangboard system is made to be supported by a wood board in the back.

I glued two pine boards of 18mm together to get enough depth for the screws to grab on.

What is provided:

• Top+pocket sloper modules, oriented horizontally, of each of those angles:
  • 20 degrees
  • 35 degrees
  • 45 degrees

• 10mm + 15mm + 20mm two and single finger pocket module

• 10mm + 15mm + 20mm 4-finger edge module

• Rotatable ("SloperC") dual angle slopers, that can also be used as mixed sloper/pinch/gaston exercices depending on the rotation you select. Those are held by a large bolt, allowing to chose the needed angle.
  • 25 and 30 degrees
  • 35 and 40 degrees
  • For those, you need extra hardware, see below
  • To print them, split the STL using your slicer and print as 2 parts.

• A “baller”, that is a round ball shaped submodule for the rotatable slopers base platform

• A “Claw” training, a bit experimental. Those are currently a bit needlessly painful on the tip of the fingers.

• A drilling template STL in order to easily position the screws on your board

How to print + post process:

• I'd recommend minimum 5 or 6 walls, with some strong infill. I like to use honeycomb because it is a non-crossing infill allowing consistent fast printing, Here 25% to 30% should be ok.
• Use fuzzy skin 0.3mm/0.3mm. In some cases this can be sped up by only applying it at certain height ranges or with a volume modifier (example in 3mf files)
• Use a rough wood rasp on the areas where you'll place your fingers to make the surface sticky.

If you want to design your own compatible modules, the dimensions are as follows:

• Each block is W10cm x H11cm
• The screws are at a distance of:
  • 20mm from the sides
  • Top row : 20mm from the top
  • Bot row : 30.4mm from the bottom (Because of the extra space for the screw attachment)
• If you want a base platform model, you can just cut off the front of the 4-finger edge model.
• If you want a base notched rotatable platform model, you can also just cut off the front of the rotatable slopers.

🔩 Hardware needed: 

• 4x 3mm to 5mm shaft countersunk wood screws per module (You could risk only using the two top ones for each, but I didn't)
• Thick wood board with the dimensions of your choosing, depending on what you want to practice and the layout you chose 
  • e.g. 80cm x 22cm for an 8x2 grid of modules. On my photo I have extra to attach it to the wall without having to hide the screws behind the modules
• If you want to use the adjustable sloper or “baller”, you need for each 1x M10x50 to M10x60 bolt and 1x M10 nut+washer. You'll also need a socket wrench able to reach inside the hole to tighten it.

🧵 PETG/ABS recommended
