Threaded rod joint using aluminium square tube

Just a quick and robust threaded rod joint idea I wanted to share in case someone is looking for inspiration. I needed simple cube shaped construction and decided to make it out of threaded rods. It’s not accurate since holes are in offset, but I didn’t need actual cube so I am fine with it. I built¬†lightbox¬†with this cube.

How to make simple threaded rod joint?

Picture says it all. I bored 2 holes on each side with little offset so both rods can go trough. Also made holes bit off center so the third one can be inserted into aluminium square tube itself. My square aluminium tube was exactly tight enough- so the third threaded rod fitted snuggly into it’s place.

You can look at this 3D printer version on Thingiverse- which is quite nice and much more accurate.
