Very stable corner connector for three 2020 extrusions
Great base for any 3D-Printer project up to ~40x40cm size :)
It's imho better and definately more precise than the comercial aluminium connectors I used before this. It's much more rigid than you might think!
You need usable bridging to print it niceley :)
I recommend to print them from good ABS or PETG (tested, works great!) or anything else very stable - cheap PLA ist not recommended, except maybe for small printers.
