After a year of waiting, I finally got to test my next iteration of 3D printed climbing holds. By using Rigid.ink's Carbonyte filament, I was able to harness the hardness and texture of carbon fiber combined with the durability of Nylon 12.
You can find Rigid.ink Carbonyte filament here : http://bit.ly/carbonyte
MatterHackers also has a similar filament : http://bit.ly/CarbonXNylon
