After 2 months of using it full time, I am really satisfied with my Redox Manuform keyboard (https://www.prusaprinters.org/prints/23522-redox-manuform). It is very comfortable to type on.
The only downside is that it is quite bulky when i need to go on business trips.
This is why I decided to build a second keyboard which would be flatter for better portability.
Instead of the handwired version, I started with the PCB (Rev1) version of the Redox keyboard with the following modifications:
Case sides are curvy.
Some of these modifications come at a price: more filament is used and some slight sanding is required on the top of the keyboard since you cannot benefit from the buildplate surface for getting a smooth top. The overall keyboard is also slightly thicker than the original design.
In order to bend all the diodes I used a very simple bending jig: https://www.prusaprinters.org/prints/23523-1n4148-diodes-bending-jig
On the left side, the arduino Pro Micro gets soldered upside down. I printed 2 spacers to add to the standard header to get the proper height.
As the micro USB connectors on the Pro Micro are notoriously weak, I preemptively added a good dollop of epoxy on them to reinforce that location.
Printer Brand: Prusa
Printer: i3 MK2S
Rafts: No
Supports: Yes
Resolution: 150µm
Infill: 20%
Filament: No Name PLA Black for body, transparent for bottom
Notes:
Slight sanding of the main body with wet sand paper up to 3000 grit.
All parts should be rotated and printed in their final orientation (ie: same orientation as when the keyboard is in use)
