1U to 3U Eurorack Format Changer

I'm making the jump from my intellijel palette to a conventional 3U eurorack case, but still had a few 1U modules I wanted to use. 

This model can accept threaded inserts, or square nuts, and ranges from 6HP to 40HP (actual width consumed in the rack is 2HP wider)

With the larger sizes, make sure to populate and screw down the top and bottom module rows before installing the middle, the top and bottom module will help provide additional rigidity for the converter. 

I had the best luck printing it on it's side with organic supports
