I've recently purchased several off of eBay. I could post some measurements.

That said, you can get one for $40 or less. I've got an extra one I'd sell for $30. For me it would take a LOT more than $30 of labor and materials to make one from scratch, but if that's your thing go for it.

I'm personally seeking out the dimensions of the two lens assemblies. I'd build 3D models in Cinema 4D to have them 3D printed.
