Sinc Keyboard Case
Here's case design file for the Sinc. The .ai files have multiple layers to toggle on/off to generate the correct set of plates/mid-layers/etc.
3D Printed Middle Layers
These are the STL files in the repository. These are an initial version of the design, as a more complete design with tighter cutouts for USB-C and TRRS ports will be made.
New Enclosed Design
In the enclosed-case folder, there are STL files for a new design where the FR4 switch and bottom plates are used but have their sides covered. The top shell has been designed to be threaded into directly from underneath using long M2 screws.
For the Rev. 2, you will need M2 screws that are 16mm in length. For Rev. 1, due to the thicker mid layer, you will need 20mm screws.
