You'll want to build a case for your synthesizer next. You can get creative here and repurpose an existing enclosure, build something from scratch using wood, or even repurpose a cardboard box!
Cardboard is great to work with because it is so easy to cut and poke holes for your controls. I designed a template you can use if you want to follow this design. You can print out the template and use it to trace where to cut for the pads, knobs, switches, and ports. Or, if you have access to a laser cutter, cut out the pattern directly!

Assemble the synthesizer into the box starting with the Trellis keypads and PCBs. You can make a small frame to hold the PCBs in place using 2.5mm nylon screws and nuts. Here is the template file for the frame, with holes that match the outer template.
