Egg-On-Rice-Controller VS pangolin

This is actually a stacked acrylic design, that I got cut through Ponoko. I used LibreCAD for it, which meant just drawing holes on each piece of acrylic to get cut. The Egg On Rice controller uses the same kind of design, and it was actually my original inspiration: https://github.com/b1nc/Egg-On-Rice-Controller

Sure thing. https://github.com/b1nc/Egg-On-Rice-Controller

I'm a fan of using aluminium extrusions & laser-cut aluminium panels.

Check out my Pangolin design. https://github.com/henrebotha/pangolin It uses aluminium extrusions (8020 profiles) to make a sturdy frame. Even if you still want to use acrylic as the structural material for the panels, having a sturdy (and cheap!) aluminium frame will help a lot.

I have an enclosure design that uses laser-cut and 3D-printed parts, and keyboard switches. https://github.com/henrebotha/pangolin

Here's my DIY enclosure design. https://github.com/henrebotha/pangolin It should be doable for €100 or less, depending on various factors. It doesn't require special tools; all the parts are either off-the-shelf, or laser cut/3D printed by online services. No weird screws or anything like that. I really tried to make it easy to build anywhere in the world.

I designed a cool DIY metal one that supports an acrylic top so you can add art. You don't need anything special, just a screwdriver; the parts get laser-cut. https://github.com/henrebotha/pangolin

The latter option is better, because it guarantees perfect operation of any MX-style switch, but it requires a specially-designed (or, at minimum, modified) enclosure. Especially if you want the buttons to not be super duper tall. I designed such an enclosure (https://github.com/henrebotha/pangolin), but it's a hassle.

I don't love fully 3D-printed enclosures, so I designed a metal one that uses aluminium extrusions for the frame and laser-cut aluminium panels for the top & bottom. You can take a look at it, you might learn some stuff. https://github.com/henrebotha/pangolin

I don't sell 'em, it's open source plans to make your own. Basically just order some parts online & assemble it with a screwdriver. https://github.com/henrebotha/pangolin

I can guide you in making one, if you want. Infinite possibilities for customisation. https://github.com/henrebotha/pangolin My build worked out to 26 mm thick, but you can go even thinner if you e.g. don't use an acrylic cover, or choose a thinner sheet.
