TrusSystem

thingiverse

You'll have all the parts you need to create a truss structure using any 8mm rod or tube with this kit. I personally opted for anodized aluminum tubing but know that the well-regarded stainless steel 8mm rods commonly used by RepRap users will also do the trick. It's worth noting that this structure is both very sturdy and impressively light. The instructions require you to have parts Truss-22, Truss-24 and Truss-31 with a 2mm brim for them to stick to your Kapton bed. Use M3x16 screws for most parts, except the triangular top and bottom assemblies which demand the use of M3x12 screws.
