The Zenestra is a modular keyboard case which allows you to easily add, replace and design your own parts.
[!WARNING]
The Zenestra project is currently in pre-alpha status. Prototypes for the case are in production, and PCBs for the project are still in development. These files are being made available for open source development purposes, so that tooling can be developed. If you are a customer, please hold off until the official project reveal before developing or ordering things based off of these files.

The Zenestra project consists of a premium keyboard case, several kit options, as well documentation and templates to create your own PCBs and case accessories from, the latter of which are contained within this repository. It was inspired from rectangular DIY kits some creators in the community have made in the past and is meant to lower the barrier to entry for designing your own keyboards: you won't have to think about the case anymore and can focus on just the PCB design.
Using tools like Kicad (with the included template) or Ergogen, you can get started with relative ease. Guidance on dimensions and PCB design considerations can be found in this document.
The Zenestra case will be available at splitkb.com in the future. While meant for split keyboards, it can also be used for macropads, numpads, game controllers and other uses, and as such will be available individually and in sets of two.
The Zenestra project makes the following files available:
You can place the zenestra-template folder into your own Kicad installation's template folder. Please see the Kicad template documentation on where these files can be placed.
[!NOTE]
The template requires Kicad version 7.0.0 or higher.
If you then Choose File > New Project > New Project from Template, you'll be able to select the newly added template to get a head start when creating PCBs for your new case.
The following projections are available in the projections folder which you can import into Kicad, Inkscape, LibreCAD and many other tools to design case parts with:
pcb-edge-cuts.dxf: An outline of the PCB. You can import this into your PCB design program to use as edge cuts. It's simply a 150x100mm rectangle with rounded corners.pcb-mounting-holes.dxf: The mounting holes to use for the PCB. You can import this into your PCB design program in a layer such as User.Drawings or Eco1, to put mounting holes at the locations marked by the circles.pcb-keepout.dxf: An outline of areas where the PCB and tripod thread can touch the PCB. You can import this into your PCB design program to use as B.Courtyard, so you can avoid placing components at these spots on the bottom of your board.top-shallow.dxf: An outline of the PCB with mounting holes you can use as a template for top layers that cover only the PCB, but not the rims of the enclosure.top-wide.dxf: An outline of the case with mounting holes you can use as a template for top layers that cover both the PCB and the portion of the case up to the chamfered edges.top-full.dxf: An outline of the full case, handy to use when designing a foam cutout for a carry case and such.inside.dxf: An outline of the inner profile you can use to design an inlay for the case, such as a sound dampening mat. It has an offset of 0.5mm all around the wall to account for the inside fillet, and there's a cutout for the tripod mounting hole.bottom.dxf: A projection of the bottom showing the case outline, mounting holes and bolt recesses, SKUF rubber feet recesses and the tripod mounting hole.emblem.dxf: A projection of the case's emblem.Do mind that all the files do not include kerf. If using it with a laser cutting service, inquire for the kerf setting to use. If kerf is required, you may need to modify your files, or ask your supplier to modify them for you.
Here's some guidance on important dimensions:
