5 Climbing Holds from one Rock of The Bay of Fundy

For all my climbing hold prints, I've primarily used PETG, which works best when it's dry at 0.16 layer and 2-5 fuzziness. ABS is a good alternative. I’ve also tried PLA, which performs well indoors as long as you’re not too heavy and avoid dynamic moves. Avoid overtightening the holds, and use a washer when necessary.

The white climbing hold shown in the image is made of PLA.

I design climbing holds in Bambu Studio. Using AI to transform real rock images into 3D models in the MakerLab.

This version was crafted using rocks I discovered on my recent trip to the Bay of Fundy in New Brunswick.

This 3D-printed climbing hold is provided without guarantees of print quality or structural integrity. Always inspect holds before use.

I do not suggest using supports. I’ve tried printing with supports, and it’s better without them. You may need to burn some filament to smooth out the surface for a better grip and finish of the big jug.

• Use a washer with the mounting hardware to ensure proper installation.
• Use one Flathead wood screw number 8 ( minimum 3 inches in length for secure mounting )
• Do not overtighten!

Crush it safely!
