BSA BTTF Pinewood - remix of mcarson74's

Remixed from mcarson74's well-designed pinewood-interpretation of Back to the Future:

Minor changes. The Mr Fusion detail-piece was a bit corrupt, so I reworked that one from scratch. Also modified the mating portion of the car shell & the Mr Fusion detail, for ease of printing and assembly.

The Mr Fusion piece has a lot of very small details - recommend printing in resin.

I also included a template that I used to mark cut-lines on my pine block.
