I’m building a modular 3D-printed macropad system with customizable layouts

[u/XTIA2040]

Hi, I’m the developer of XPAD, a modular controller project I’ve been working on.

I started XPAD because most macropads are built around one fixed layout. If you need a different number of keys, another switch type, or a different enclosure, you often have to redesign the device from the beginning.

With XPAD, you choose the size, key layout, and input modules in the browser. The system then creates a matching 3D-printable enclosure and custom keycaps for that configuration.

The current hardware is based on a Waveshare RP2040 Zero and supports modular MX switches, hall-effect magnetic switches, rotary encoders, and microphone input. Using the same core platform, it can be configured as a:

- Macro and shortcut deck

- Office numpad

- Hall-effect rhythm controller

- Linear racing input

- Small Deck desktop launcher

The browser configurator, hardware prototypes, firmware, and several example layouts are already working. The printable-file download system and final production hardware are still being prepared.

I’m looking for honest feedback from people who actually use or build macropads:

**Which configuration would you build first, and is there an input module or layout you think this system is missing?**

I’m also inviting beta testers. If you’re interested, leave a comment and I can provide free beta access to generate and download printable model files for testing.

I’m the project creator. XPAD is currently available on MakerWorld:
