Angle Bracket Suggestions

Hi everyone,
I’m working on CADing the electronics box for this upcoming season (I’m hoping to have it be all modular). I normally do electrical and programming so I’m not too used to MCAD. I found an angle bracket on (McMaster Carr part number 1564A1), but they don’t have a CAD model :(. Does anyone have any suggestions for good angle brackets with CAD models or drawings to make CAD models from?


How about here, under extrusion.
