This is a case for the Redox ergonomic keyboard, using the PCBs from FalbaTech. There were some things about Matt's design that bothered me, so I tried to fix them here. These are the changes I made:

• Screws together from the bottom, not the top
• Mounting holes in the bottom for keyboard feet or tenting legs
• Switch holes oriented correctly for new FalbaTech PCBs
• No screw hole at the front, for better underglow appearance (still very solid and held together properly by the remaining screws)
• Alignment bars to strengthen the sides of the case and make sure it goes together properly
• Holes fit around the connectors properly (see below)

This case may not fit your keyboard depending how you assembled it! This is because of the last point above. The tolerances on the connector holes aren't very big. You will likely need to use the Fusion 360 file to modify the files for your specific keyboard. At the very least, you should print a small slice of the case, enough to confirm that the connectors will fit. Do not print the full case until you do this!

Also included are some example keyboard feet. These should be printed in something like Ninjaflex. The MiniFoot_short, MiniFoot_med, and MiniFoot_tall files stick out 1 mm, 1.2 mm, and 1.6 mm past the bottom of the case, respectively. I included several different lengths in case your print bed isn't perfectly flat and the case comes out slightly warped.

Finally, I've included .f3d and .step files in case you want to further modify this.

See notes

For any parts printed with translucent filament, use 100% infill. It looks so much better. Otherwise, use 20%.

Only the bottom parts need supports, for the ports at the back. The top does not need supports.

You will need:

• 8x M3 nuts
• 8x M3x8 screws

Insert the nuts into the slots in the top half of the keyboard. Optionally, you can use hot glue to secure them in place. If you do this, put a screw in temporarily to align the nut.

You may need to clean up the screw holes. I had to scrape some plastic off of some of the indents to make the switches lock in properly.
