## Description

For all the DIY keebfans in the house here is a super sleek and sturdy **4-Key Aluminum Keypad Shell in Silver**, the perfect base to begin your custom keypad project. You provide the PCB in the housing and bolt it into this base. Makes for a prettier build with more protection than just layers of PCB or acrylic. While it's designed for a custom PCB, you could also just snap in 4 keys and 'free wire' them. Comes with one anodized silver aluminum enclosure and a clear acrylic bottom that screws on with two M2 bolts.

Designed for use with any "Cherry MX" keyswitches or compatibles, like Kailh or Gateron.

**Note:** This is ***just*** the keypad shell. Don't forget to grab some [keycaps](https://core-electronics.com.au/#) and [switches](https://core-electronics.com.au/#).
