About this 3D model

Plastic connectors for Aluminium* square tube. Or printable square tube. Similar to those used to assemble furniture from the homeware store. Qubelok being one type http://www.fairlite.com.au/qubelok.html There is a zip of the STLs down the bottom of the list. (It doesn't have the new 45/135 degree ones mentioned below) One-inch or 25.4mm profile as writen, but you can change size via OpenSCAD. The SCAD has callable modules to model the connectors and the tube profile and a print module to split a part in half and rotate for 3D printing. Work in progress, probably needs refining. I'm also working on a hollow version so cables etc can pass through the joins. But no promises. * aluminum if you don't speak true English ;^} Someone asked for 45 & 135 degree joiners, see SqTubeJoin-45.stl, SqTube-Join-135.stl and the A & B versions split in half for no-overhang printing. I also just uploaded versions of the 45 & 135 with a flat face, rather than that bit sticking out, see SqTube-Join-45-Flat.stl, SqTube-Join-135-Flat.stl and the A & B versions split.
