Schematic & PCB
I made the pcb in kicad
3d Case
The case consists of 3 parts, the top cover, bottom cover and a stand that attaches to the bottom. Everything is connected using m3 heat set inserts and screws. I made the case in onshape. here's the link for the onshape project:- https://cad.onshape.com/documents/0f47473beb05ba1bc00654df/w/e1cbcdd202a0a0f5e24ed7bd/e/dbeb9d6fbd234f685e1c68c6

Questions
How big is the MIDI PCB?
It measures 104.8 × 150 mm and has 2 copper layers, 1.6 mm thick.
What parts does the MIDI use?
54 parts. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the MIDI KiCad files?
From the FlazeDev/FlazeMIDI repository on GitHub, at the commit this page was made from: the board is FMIDI/PCB/MIDI/MIDI.kicad_pcb and its schematic FMIDI/PCB/MIDI/MIDI.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the MIDI design in my own project?
Its repository states no licence, so its author keeps all rights: ask FlazeDev before reusing the design.
