Overview

The Glorious GMMK 3 is a full-size (100%) barebones mechanical keyboard kit built for users who want to handpick every aspect of their typing experience. As a barebones kit, it ships without switches or keycaps — instead, it provides the foundation: a solid chassis, aluminum switch plate, pre-installed stabilizers, and hot-swappable 5-pin MX sockets across the entire board. This means you can install your preferred switches by simply pressing them into place, and swap them out later for a completely different feel without any soldering or technical skill required.

What sets the GMMK 3 apart from many barebones kits is its Modular Gasket System (MGS), which offers nine individual mounting points where gasket inserts can be added or removed. This lets you control how much flex the board has, directly affecting the typing feel and sound characteristics. Two layers of sound-dampening foam further refine the acoustics, reducing the hollow, pingy sounds that can plague less refined keyboards. The aluminum switch plate provides a stable, crisp keystroke foundation, and the programmable knob adds a convenient rotary control for volume, scrolling, or custom functions. Connectivity is wired USB-C, prioritizing reliability and low latency. For keyboard builders who want a full-size layout with meaningful tuning options, the GMMK 3 delivers a thoughtfully designed platform to build on.

Key Features

9 Points of Modularity: A highly modular design makes it easy for you to swap the GMMK 3's parts, tailoring its look, sound, and feel to your exact preference.

Modular Gasket System (MGS): Easily customize the GMMK 3's internal gaskets with a simple building blocks-inspired design for a firmer or more flexible typing feel.

Programmable Knob: Twist to quickly adjust your device's volume, press to play/pause media, instantly mute, or create a custom action with Glorious CORE software.

5-pin MX Hotswap Support: Plug and play with our wide range of Glorious MX switch styles to define your GMMK 3's typing sound and feel, no soldering required.

Sound-Dampening Foam: Two layers of dense foam within the case absorb unwanted resonance for a satisfyingly clean acoustic profile.
