These allow a sliding Tee or "H" joint for EMT construction. I used them on my portable solar panel project for the legs and they work great. You might want to up the perimeter walls a bit for added stiffness, I used 4 with 25% fill in PLA. Use the Conduit Connector fastener from my website for easy EMT construction. https://targetforge.net/shop/ols/products/34-emt-conduit-hardware/v/CND-TO
Cheap, easy, adjustable!
Tons of uses, a table, solar panel legs, etc..
One M4 X 12mm screw and nut for each bracket.
