This is small library for generate T-slot 40mm profile, this was written using "blueprint" obtained from ali seller. You can you can use this lib to generate profile alike (with central hole) 40_profile(tolerance=x,sections=y) or just 40_profile(x,y) 40_profile_no_hole(tolerance=x,sections=y) or just 40_profile_no_hole(x,y) 40_profile_no_hole_no_slit(tolerance=x,sections=y) or just 40_profile_no_hole(x,y) (without central hole) plate_40_profile(tolerance=x,sections=y) or just 40_profile(x,y) plate_40_profile_no_hole(tolerance=x,sections=y) or just 40_profile_no_hole(x,y) plate_40_profile_no_hole_no_slit(tolerance=x,sections=y) or just 40_profile_no_hole(x,y) it have polygone modules shown on picture t40(); this is typical 4040 corner t40expansion_insert(); t40plain_side(); t40_no_hole(); t40expansion_insert_no_hole(); t40plain_side_no_hole(); t40_no_hole_no_slit(); t40expansion_insert_no_hole_no_slit(); t40plain_side_no_hole_no_slit(); using polygones don't forget to add a 6.8 mm hole byself
