Climbing Holds

https://youtu.be/P5djan6Bc7M I created these for my 2-year-old but made them large enough so he can grow into them. I printed them personally at 30% infill with a 3mm shell. They were able to hold my weight, as I weigh 200lbs. You may also want to try printing them with "fuzzy skin" from the experimental section of Cura. Additionally, I applied primer to them and then painted them using textured spray paint.
