These are the files I made to print my ecto goggles from Ghostbusters. Loosely based on Paranorman's measurments. My execution is not totally accurate but good enough for my purposes. Built to minimize support structure so pieces will need to be screwed/bondo'd/plastic welded/whatever your preferred process.
Included are .obj files which will need to be scaled by 10. (1000%) I've included the files I actually exported, most of which on low quality because I will be doing much finishing anyway,
