Back in my day, if you wanted a mechanical keyboard, you had to purchase a massive IBM Model M Keyboard but now you can DIY your very own compact keyboards with your very favorite layouts to make the keeb of your dreams.
For all the DIY keebfans in the house here is a Clear Plastic 65% Keyboard Shell aka a "JKDK K68" type enclosure. Its the perfect base to begin your custom keyboard project, when you want a few more keys than a 60% - especially if you dig a translucent base that can show off your glowy LEDs. It's also a lot less expensive than a milled & anodized aluminum shell. However, it won't be as heavy, durable, and flat. That said, it's a great starter shell. You provide the PCB to match and bolt it into this base. It's also designed with a slot for a USB C power supply.
Comes with four rubber feet and mechanical screw hardware.
Note: This is just the keyboard shell. Don't forget to grab some keycaps and switches.
