About this 3D model

Hello, this is an optimized very Strong Corner Bracket/Winkel for Aluminium Extrusion Profiles like ITEM in 40x40 size with holes for M6 Screws. I optimized the structur to have the strongest layer lines, how you can see in the pictures below the lines are perfectly lined. If you want any other sizes you can write me and i will try my best ;). I put STL, 3MF for Bambulabs and for Solidworks (if anyone want to change something) in the downloads.
