Ghostbuster's PKE Meter

I made this toy based on the shoe polisher that was used in the movie. It is for my great nephew, who is now a 7 year old full-time ghostbuster.
It is still a work in progress. I added quit a few pictures to show how I did the electronics, but the scope here is just to make the case:

1. Print one of each file.
2. connect the bottom handle and bottom base with 7/8" aluminum angle; plastic is not strong enough here; glue and screw.
3. Consider drilling out the posts and replacing them with 1/4" brass rod (it's what I did because I was afraid the plastic wasn't strong enough after all the wiring.
4. I used epoxy glue throughout, and 'painted' each part with acetone to make sure nothing delaminated. 4-40 screws to hold the case together.
5. Electronics are intense, so plan well and use a strong servo. My cheap miniature servo really didn't have enough guts.
6. Allow about 30 hours for total completion, including electronics....
7. See downloads for video PKE.MP4
