I needed some legs for a table. Maybe for permanent use, maybe not. PVC tubing is cheap and easy to use. And many connection pieces are available and when glued together the connections are mighty strong.
There are already many designs for this solution. I like to make my own and have the design files, so I can modify and adapt. I know many of you do too, so I shared them here. If you want the STEPs, just drop me a line.
This design uses 32 mm tubing.
I designed this with Fusion 360. I'll add the files so you can modify it to your needs.
