3D Printed Foot Holds

I set myself the challenge to design & 3D print foot holds for bouldering. Being a member of Red Spider Climbing I had a fairly decent idea of what I wanted them to look like. The design brief was: Reliability In bouldering we learn to trust loading our weight onto small foot holds. I needed […]
