Are you all homecockpit builders? What project are you working on?

Starting from this we will be able to open new sections and discussions to exchange experiences and solutions on specific topics.

I’m working on a long-term project (about two years so far) to build a home cockpit of a Piper Arrow III (PA28R-201).

Getting the measurements of avionics instruments is relatively straightforward, but I’m struggling with other parts, like handles and smaller cockpit elements.

For example, I’d like to 3D-print the fuel tank selector. While I can get good screenshots from X-Plane to approximate the shape and mechanical details, it’s difficult to figure out the actual size. Unfortunately, neither the service manual nor other documents I’ve found online include dimensions for these parts.

Any ideas on how to approach this?
