Having been in search of a sleek 75% layout QMK-compatible keyboard with a low-profile design inspired by Mac/Logitech MX low-profile keyboards, I found myself torn between the NuPhy Air75 V2 and the Keychron K3 Pro. Eventually, I settled on the Keychron K3 Pro Low Profile, equipped with Red Gateron MX low-profile switches.

However, upon using it, I noticed that the sound produced by these switches was somewhat understated, which is expected given their low-profile nature. While the click sound was satisfactory, I sensed potential for improvements to achieve a more resonant and satisfying 'thockyy' sound

The project itself wasn't particularly challenging, given the abundance of tutorials available on YouTube. However, I would rate its difficulty at around 3 out of 10 on the scale.

Despite its moderate complexity, it turned out to be intricately detailed and time-consuming, requiring approximately 5 hours for completion. Below, you will discover a detailed parts list, a sound test, along with comprehensive instructions and accompanying images.

    Following extensive use of my keyboard, I recognized the necessity for a palm rest to enhance my setup. However, I encountered a significant issue: the palm rest failed to securely attach to the keyboard. This became particularly problematic during cleaning or reorganization processes, as the palm rest would not remain affixed to the keyboard when moved. To address this, I undertook the design of a specialized frame intended to seamlessly integrate both components.

    The development process required the iteration of six different versions, each incorporating incremental improvements to achieve the desired functionality and stability. A notable challenge was the limitation imposed by the size of my 3D printer's build plate, which necessitated dividing the design into manageable segments. This led to the invention of a T clasp mechanism, designed to securely unite the segments into a cohesive whole.

    Furthermore, in pursuit of enhancing the aesthetic appeal of my keyboard setup, I opted to replace several keycaps with alternatives that offered a more visually pleasing appearance. In an effort to contribute to the community and assist others who may face similar challenges, I will be making the frame design available as a .STL file for unrestricted use. This initiative aims to provide a practical solution that promotes both ergonomic benefits and an improved aesthetic for keyboard users.

    I have also resolved to name this keyboard the KC 6H, a decision influenced by the extensive six-hour endeavor required to lubricate each key, as well as the iterative process of crafting six distinct versions to achieve a perfectly fitting frame.

  • 1
    Keyboard Disassembly.

    The project commenced with a meticulous disassembly of each switch, involving a careful separation of components in order to lose any of the components.



  • 2
    Lube the switch.

    A thorough oiling process was undertaken, addressing both the individual components and the integral spring to enhance overall sound.

  • 3
    Assemble the keyboard to the framework.

    The switches were unskillfully reassembled, lacking precision at every step due to it being my first time.
    The entire assembly was then mounted back into the keyboard framework.
