Structural Pipe 3/4" Steeltek Fittings For Furniture and other projects

thingiverse

I designed fittings for a T, Coupling, and Flange to connect 3/4" structural steel pipe (or SteelTek pipe from Lowes). All the parts were printed in ABS with a 0.6mm nozzle at a 0.4mm layer height. I tested each fitting to ensure they worked properly and used them to build a mini desk for a keyboard and mouse. Each fitting has holes for 1/4-20 screws, which I drilled and tapped using short 5/8" screws to secure the pipe firmly in place. The T fitting requires two separate parts - one inside and one outside - as well as 2x 2.5" long 1/4-20 screws and 2x 1/4-20 nuts. Alternatively, you could drill and tap for M6 screws instead.
