Hi and welcome, bkraco!
What else do you need to fit in that case?
Did you look at the Doepfer cases (http://www.doepfer.de/home_e.htm) ?
Both plain wooden and very solid flight case types in several sizes.

I play in a semi-frequently touring grindcore band, and 2016 is looking to be very busy for us. I'm looking for recommendations for a portable and durable case to fit a 60mm depth Doepfer VCO module, with at least 44HP. Since it's non-studio, the more portable the better, as we'll probably have to fly at least once next year.

If this is the wrong section, I apologize, this is my first post.

Thanks!
