Migrated to: https://www.printables.com/model/544151-case-for-deftaudio-midithru4-midi-splitter-wall-ad The MidiThru/4 splitter from Deftaudio ( available at https://www.tindie.com/products/deftaudio/midi-thru-1in-4out-splitter-pcb-or-a-kit/ ) is a really nice little kit, and about the cheapest real splitter box you'll find. However, it needs a case, and I decided to make a custom one, instead of boogering up a metal box for the purpose or something.
