+# Wat
+
+This is a laser cut case for the [Corne split
+keyboard](https://github.com/foostan/crkbd) which turns it into a single object.
+
+Why on earth would I do that? I love my corne keyboards but they can be a bit
+awkward on, say, the couch. I wanted something to put on my lap but still be a
+corne. This is, of course, inspired by the
+[reviung41](https://github.com/gtips/reviung/tree/master/reviung41)
+
+The halves are tiled by 5 degrees which has worked well for my hands.
+
+The center section is removable independent of the rest of the case, allowing
+easy access to the electronics without tearing apart the whole case. (Could also
+use it to swap out stickers or art or whatever.)
+
+More images are available in the [images/](images/) directory, including one
+version in MDF with a plywood top, and more photos of the edition featured above
+with lots of RGB.
+
+# Development
+
+I use Shapr3d for all my CAD-ish work and the source for the DXFs lives there.
+`dxf/Core.dxf` is an export of that file.
+
+# Use
+
+## Cut Parts
+
+`dxf/All Parts.dxf` contains all the individual parts. When I cut my cases, I
+drag the `All Parts.dxf` file into the Glowforge site and pick out the pieces I
+need. 
+
+The thickness of the parts is really dealer's choice. I print the top and bottom
+plates in 3mm. For a lower profile, I use two 6mm middle plates. My usual build
+is a high profile which uses two 6mm middle plates and one 3mm middle plate.
+
+## Bill of Materials
+
+The unibody case is designed to hold a Corne using the standard FR4 switch
+plate. So, perhaps obviously, you'll need one for those.
+
+
+For the case itself:
+* 14 standoffs. (The case is designed for round standoffs. Hex standoffs will
+  not fit.)
+* 28 M2 screws, at least 8mm long
+* 10 screws to hold the keyboard itself
+* [small trrs cable](https://www.mouser.com/ProductDetail/474-CAB-14163)
+
+I'm not going to provide a measurement on the standoffs. I know that seems like
+I'm being a bit of a jerk but there's a problem with laser cut media. Despite
+measurements like 3mm or 1/8", the plates are never that exact size. There's
+usually a 10% tolerance either way in thickness. In the end, this makes the
+exact thickness of the plates, and thus the length of standoff needed, somewhat
+non-deterministic. For instance, I cut one out of two 6mm plates and another out
+of one 6mm plate and two 3mm plates (I ran out of 6mm). The one with two 6mm
+plates needs 11mm standoffs while the other needs 13mm standoffs. The only way
+to know what size standoffs you need is to cut the case and measure.

+This keyboard uses a bottom plate that is matte on one side, clear middle
+plates, and a top "milky white" plate. The acrylic was sourced from [Houston
+Acrylic](https://houstonacrylic.com) and cut on a Glowforge.
