Summary

This is a hold for a rock wall system that uses standard bolts

Instructions

I have not fully tested it but when printing use at least 4-5 shells, I am testing different % of object fill and will update when I find a good mix.
!!!!WARNING!!!!
Climbing can be dangerous. All climbing hold that are tested on your own, is your responsibility and should be tested in a safe and controlled environment.

I just finished testing on the holds and it will depending on the use of the holds, here are the minimum requirements;
For just a hand hold: 4 Shells with a 20% object fill, but if the hole on the wall is bigger I would suggest 5 shells.
For Hand and foot hold: 5 Shells with 35-40% object, also if the wall has a bigger hole I would put 7 shells.
Remember these are just the min requirements!

The biggest problem that I had was when i would tighten the bolt to the wall and the wall hole was big enough to fit the bolt and 4 shells so with the lower object fill it would pull the inner shells out of the hold.
