Finger training board

Easy to print portable rock climbing or grip strength finger training board. 10MM, 15mm, 20mm, & 25mm edges, added “furry” appearance that gives the holds a bit more grip. Its plenty strong for most advanced to elite level fingers, although if you have some god like strength I suppose you could print 100% infill. Holes are 9.5mm, any rope up to 9mm should work.
