Here's my version of a Phase One Clone Specialists from the Star wars the clone wars tv series. I'd scale it up around 190% to fit a persons head. The Macrobinoculars should just fit in the cut out area of the ears and a 5 mm dowel should be able to pin it in place.

I printed mine at 180% and unfortunately can't fit my head in, but 190% should fit(I was trying to conserve filament and undersized it, its off by like a 1/4 inch), however it still should make a good display piece once finished.

be sure to post a make and check out my other models.
