Thanks for sharing those other designs, @gravescolleen
What I was asking about was a 3D model of the Makey Makey itself, or at least the dimensions. Having access to that makes it far easier and quicker to create or modify an existing design to fit the Makey Makey. (The other option is to measure the board directly, but this requires some measuring equipment and skill.)
We have used a similar process to design the enclosures for many of our projects. Information from the printed circuit board design can be used to create a 3D model that accurately reflects the location of mounting holes, lights, buttons, etc. We can then insert this into a CAD program and virtually build an enclosure around it.
For example, here is a series of screenshots from the Sip and Puff Switch. The first image is a model of the PCB. This one has a high amount of detail, but that isn’t strictly necessary.
The second image shows a screenshot of the bottom of the enclosure, with cutouts for the adjustments, and inputs and outputs. Minimal trial and error is necessary to get the locations correct.
The final image is a screenshot of the completed enclosure with labels, etc.
This can be useful whether designing a 3D printed enclosure, or a laser cut one like the one you linked to, or someone other manufacturing technique. We can probably also help create this if for whatever reason it isn’t available.
