flexible dome connectors
thingiverse
Create economical, flexible dome connectors using this DIY method! Inspired by WilliamAAdams' simple tetrahedron (http://www.thingiverse.com/thing:8306), these connectors offer ease in domeraising and graceful equalization due to their flexibility. Unlike traditional connectors, they require no absolute precision in strut lengths. For instructions, gather vinyl tubing, nuts, bolts, and cut dowels or poles according to the desired strut type (we used 3/8" dowels). Cut tubing into 2-3" lengths, drill holes, thread washers and tubing on a bolt, cap it with another washer and nut. Space tubing out to form a hexagonal shape, then tighten. Assemble your dome or sphere by sliding struts into tubing - leave one tube empty for pentagons. A 2V icosahedron requires 26 connectors.
