interlock

interlocking bracket for 3030 extrusions, with one style for right-angle and one style for adjustable angle. Modifying this design is probably for experienced designers only. If that's you, LOTS of awesome variations are possible. Compared with the popular OTS parts, this design is ► not fully fixed, can slide along ► requires less hardware, just an M6 screw/nut ► far cheaper!!! great for prototyping ► flush with the aluminum beams See Mcmaster part no. 47065T191 to compare aluminum OTS design ► STEP files: I exported 2 types while several useful variations were sprouting. Type 1 is for 90 degree configuration and Type 2 is for adjustable angles on the attachments.
