The CAD designs are really starting to come together. I've been noodling around with paper sketches for months to figure out how to breathe aesthetic joy into what is mostly a Design For Manufacturability (DFM) task. Screws don't screw themselves, and they're particularly costly if you put them in an awkward / uncomfortable place. Another design goal is to make any hardware extensible and useful outside of this one specific use. I've thrown out a few lowest-cost solutions in place of a design that you can open, take apart, mod, and put back together without a headache.

In additon to the standard Eurorack format, we're focusing on a low cost DIY design that you can source yourself, as well as a high end bent-metal design that should really shine.

 

Here is the flat DIY design. We chose laser cut / CNC milled acrylic because even if you don't have the equipment yourself, there are plenty of places and makerspaces to fabricate the designs yourself.

In this rendering you can see how dead simple and implementable this design is.

We're currently working with a metal-forming house on the metal case design. This is a first draft. Our mechanical engineer has never done a bent-metal design, so I'm sure we're going to get a lot of industry best practices from the manufacturer. We added a punch-out in the rear to future proof the design and allow the internal electronics to be modded. I like the way the acrylic back panel shows the insides, but we're going to also offer black for people who think the insides of electronics are unsightly. The side panels are going to be a choice of acrylic or wood. We're waiting on some suggestions for captive nuts / fasteners / threaded tabs before we do that cad work.
