The Iris Ice Project

The Iris Ice Project is a build of the Iris keyboard with custom made case composed of a 3D printed switch top plate, a translucent laser cut acrylic middle plate and a brushed still bottom plate.

Backlight LEDs are mounted reversed to create a cold white underglow. The TRRS cable is also custom made to fit the right size. Keycaps are from the SA "Ice Cap" keyset from signature plastic.

Here is the result:

In this repository, you will find all the material needed to reproduce this build.

Build List

Here is the list of material you'll need for this build:

This build also assume that you have:

  • A solder iron
  • A 3D printer (or a way to order printing jobs)
  • A laser cutter (or a way to order a cutting job)
  • The bottom metal plate is ordered on LaserBoost

Build Log

Top Layer

  • Print the top-left.stl and top-right.stl.
  • Sand each piece to remove the printing lines and get a smooth surface
  • Apply 2–3 layers of primer
  • Apply 3 layers of paint
  • Apply 2-3 layers of matte finish
  • Using the pointy tip of a solder iron, insert 5 M2 inserts into the screw holes of each case
  • Insert the switches

PCB Assembly

  • Follow the Iris Build Guide
  • [Optional] Use peel-a-way sockets to solder the controller
  • When it comes to the LEDs, solder them on the bottom side of the PCB, before inserting the switches. It is better to fold the led 90° so it can fit better in the case. You may want to fold them on the opposite direction as on the picture below though
  • Align the PCB with the top layer switches and solder

Middle Layer

Cut 2 pieces in the acrylic using middle.dxf. The kerf is assumed to be 0.09, make sure to edit it if your laser cutter requires a different setup.

Bottom Layer

Go on LaserBoost and upload the [bottom.dxf] file. Select "Stainless Steel", "304 Stainless Steel Shiny Finish", 3mm. In the "special request for this part" text area, write:

Please brush the edges. Add countersink to all the holes in order to hide a GB819-M2. Make the same piece twice but in mirror (countersinks on opposite side).

TRRS Cable (optional)

Cut the TRRS cable at the desired length, and solder the plugs.
