I think I got that size about right. Stupid print driver wouldnt let me pick an exact % so I had to print with #sheets to fit on a page. I chose 6 with two pages of parts to the model so its about 3 times smaller than the original... I printed off full size and small for comparison.
I tried printing this on our new color laser printer at work and I am not happy with the result - will reprint at home. Maybe there I can pick an exact %
Here is a pic of the full size build (not done by me)
I think my major pain point will be the barrel
