Open Case - 3D Printed Keychron V1 Max Keyboard Case

For a few years now, I've wanted to design a 3D printable keyboard case… Now, with the XL I finally have the build volume to manage it!

I designed this fully 3D printable case as a replacement for the basic one that comes with the Keychron V1 Max (NOT the standard V1). Why the V1 Max? Because it is a reasonably priced ($94USD assembled) and widely available keyboard that uses open-source firmware and has a case that is OK… but could be improved.  My hope is that this open-source case design can be a starting point for further improvements.

   - You'll use:
      - PCB-Plate Assembly
      - USB daughterboard
      - 2x daughterboard screws
      - 8x cap screws for connecting case top-base

Printing Tips:

I've included all the .3mf files I used for my prints, but here are a few tips worth noting.

Universal Settings
- 0.32mm SPEED (layer height)
- 15% Rectilinear infill
- 2 Perimeters
- Textured print bed
- If you are going to work form the .3mf files provided, note that I used a mix of PLA+ (case base + knob, 220ºC) and regular PLA (case top, 205ºC). You will want to make sure the temperature and other print settings are appropriate for whatever filament you are using.

Case Base
- PLA+
- Use multi-material painting to colour the encircling motif + RF dongle slots
- Print flat on bottom of base
- Supports for daughterboard ports + RF dongle slots
- Use seem-blockers to prevent seems facing the outside of the case around the screw holes that connect the case base to the case top (see .3mf for example)

Case Top
- PLA
- Print upside down
- Modify bottom of the knob recess to have 6 perimeters for best look
- Supports for knob recess only

Knob
- PLA+
- Print upside down
- Use an Aligned Seem for smoothest results

Gaskets
- TPU 95A
- Print with holes facing up and on the flat side
- 2x small gasket, 14x large gasket

Base Pad
- TPU 95A
- Print upside down
- Use the included modifier to define the volume to be printed with infill only (I used Archemedian Chords)
