Hi @oldSkool - welcome to the Kinograph forums!
I do all my designs by myself, from optics over software to 3d-models. However, I share only what I consider to be a somewhat workable solution. So I won’t release (at this point in time) the design files of my xyz-slider, as I do not consider this to be a workable design. But, at the bottom of this specific post, you can find at least the .stl-file for the camera-body of the Raspberry Pi HQ cam, in combination with a Schneider Componon-S.
As far as I remember, I did post two core designs of my scanner, namely the integrating sphere and the 3D-printed film gate. I was able to find the film gate (including stl-files). If you scroll down a little bit in this thread, you will also find links to the stl-files for the integrating sphere.
