Slimer7's plans are the ones I used, they were great at the time(no offense to Slimer7 by any means because they broke ground at the time and opened doors as he was the first to really tackle the Slime Blower the best way at the time IMO) but many discoveries have been made since then and parts found... this photo was made available after those plans revealing the square box and flat lights as well as the longer rectangular box that was nearly impossible to see through most of the film.

this is from nick-a-tron's build

the black box was discovered to be square rather than the rectangular project box initially suggested...here's a topic showing that box
