Hey.

I am trying to build three cases, all with the same side panel dimensions, and am losing my mind trying to find a design that I'm happy with and which is simple enough that I won't fuck it up.

All cases must be 16 U; one will be 126hp eurorack, one will be 84 hp (19" with rack rails) eurorack, one will just be side panels to hold 4 Serge boats. All I want are simple cases with the same profile, on a slight incline, that won't rock or tip while I'm patching.

Can anyone recommend a free design software that will give me dimensions, angles, etc. that I can use in the real world ?
