I’m trying to look into this as I would like to build a board for myself/private gym.

I would assume 3D printed for lowest cost. I’m not too familiar with the process of hold creation; I’m sure high end is not 3D.

I’ve been thinking about approaching the guy who created these fake stones (feel like real stones), for CT Freedom Fest, to see if he can produce climbing holds at a competitive price to plastic. Game changer if so.

Imagine building a rocklike crack in the gym 🤯 #jamstr
