A custom-designed glide surface for the Logitech MX Mechanical, created to provide smooth, consistent movement for sliding wrist rests like the DeltaHub Carpio (no affiliation, just a big fan).
The lane fits around and underneath the keyboard, using its weight and geometry to hold everything in place without adhesive.
Features
Custom-contoured fit for the MX Mechanical
Smooth, low-friction surface tested with both plastic and glass Carpio feet
No adhesive, hardware, or fasteners required
Segmented design with dovetail joints for smaller print beds
Tested 0.1 mm dovetail clearance for a snug, flush fit
Available Versions
I've included several variations to accommodate different printer sizes and desk setups. All files are organized into folders for easy navigation.
Standard Build Volume: Split into three pieces for printers with smaller build plates.
Large Build Volume: Split into two pieces for larger printers, such as the Prusa XL.
No Mouse Pad: Available in both standard and large build volume versions. Removes the extended mouse area while retaining the wrist-rest glide surface.
Keyboard Only: A compact version limited to the width of the MX Mechanical keyboard.
Each version includes individual STL files for its segments, along with a PrusaSlicer 3MF project for easy printing.
Want to customize it? The complete, unsplit model is included as an STL so you can make your own cuts or adjust the layout to fit your printer.
Printing Notes
Designed for PLA. For the smoothest glide, orient the final top-layer infill lines parallel to the direction of wrist-rest movement.
Ironing is not recommended for matte PLA, as testing produced a rougher, less consistent surface.
The Idea
I use DeltaHub Carpio wrist rests with the glass feet, and while they initially glided smoothly across my PU desk mat, that performance deteriorated pretty quickly. I tried a few different solutions to restore the glide, but none worked particularly well long-term.
That led me to design a dedicated sliding surface that fits around my Logitech MX Mechanical keyboard and stays in place without adhesive. After seven prototypes, some trial and error with surface finishes, and a few design tweaks, this has been the best solution I've found so far.
It's a pretty simple concept, but sometimes that's the beauty of 3D printing: solving a very specific problem with a custom piece of plastic.
