Originally designed as a 3D printer accessory, this modular mount is perfect for OctoPrint or Klipper setups running on a Raspberry Pi—or any other compact controller tucked out of reach. It gives you convenient front-facing access to essential ports like USB, HDMI, or Ethernet without compromising your printer’s layout.
Whether you're rerouting cables for better access, building a clean control interface, or just tired of reaching behind your printer, this Keystone rail mount offers a tidy and adaptable solution.
And it's not just for printers! The design works equally well in other DIY setups—home-lab racks, test benches, AV builds, or anywhere you want to snap keystones onto 2040/4040 aluminum extrusion.
Features:
- Compatible with 2040 and 4040 aluminum extrusion
- Supports 2, 3, or 4 standard Keystone modules
- Ideal for USB, HDMI, Ethernet, audio keystones, and more.
- Snap-in design allows easy installation and swapping
- Great for printers, Pi-powered projects, and beyond
Happy printing!
