Iris Case with palm rests and tenting

A case for the Keebio Iris split ergo keyboard with integrated palm rests and adjustable tenting:

Remix credits

To design this case I remixed two models:

• Wrist rests by @MakingSingularities
• Official Iris PE case

The original STLs are included under original/.

Print parameters

I printed all of the parts using PLA on a Prusa MK4 with a 0.4mm nozzle and 15% infill.

I suggest to print the case and the palm rests top side down and on a textured surface (it hides imperfections in the first layer and makes them look more professional IMO).

Parts

Case

1. Print original/Iris PE Top Shell for 1.5mm plate.stl twice (once as-is and once mirrored).
2. Print STLs/mid-layer-left.stl twice (once as-is and once mirrored).
3. Assemble the case using 20x M2x18mm screws

Palm rests

1. Print STLs/palm-rest-left.stl twice (once as-is and once mirrored) - printed them with the top side down.
2. Attach to the case using 6x M5x12mm screws (3x on each side).

Tenting feet

There two feet on each side, a long one at the top and short one at the bottom.

1. Print the following parts:
   • 2x STLS/foot-extender-18mm.stl
   • 4x STLS/foot-adapter.stl
   • 4x STLS/foot-bottom.stl
2. Break the small pin in the foot bottoms and put a small silicon bumpers so the keyboard doesn't move around (see photos above).
3. Optional: I puts some GPL205 G00 (switch lube) on the threading as I found that it makes a lot easier to connect.
4. Insert an M5 nut into the hexagon hole in each keyboard half's top part (I used a vice).
5. Attach the rear foot adapters with an M5x16mm to the nut.
6. Attach the front foot adapter with an M5x12mm directly to the palm rest.
7. Attach one extender to each rear foot adapter.
8. Attach one bottom to every foot.

Alignment

I added a few variations for the extenders and feet bottom that add a few millimeters to help you find the perfect fit.

Cover

At first I used to carry the keyboard around with me so I printed a cover I can just put on it so the keys won't get pressed.

It's designed for low-profile keycaps but you can the source code to make it fit your keycaps - STLs/cover-right-low-profile.stl

Screws and nuts

• 20x M2x18mm (for the case)
• 8x M5x12mm (6 for the palm rests, 2 for the inner-front feet)
• 2x M5x16mm (for the inner-rear feet)
• 2x M5 nuts (for the inner-rear feet)
