Adjustable fingerboard for climbing. Starts with a 20mm ledge with none of the inserts and has 2- 5mm plates, 1- 3mm plate, and 1- 2mm plate to adjust the depth. All parts should nest well and snap together. We used about 3 feet of 10mm cordelette.

Beware of warping! I tried to make the main body really strong which meant a lot of extra material, which wants to warp quite a bit. Make sure you start with a really clean build plate, and adjust the mouse ears or brim if you need to.
