The 3D printed texture gives the scope and old fashioned cast metal look that I like.
By the way, I made my models downloadable if you guys have a 3d printer feel free, however the models are optimized for the shapeways printers so you might have to tweak them to make them work in other home printers. Just please do not mis use the files, I have placed a lot of time and effort in to making these.
Have fun.
You must quite the collection of lanyard ring tassels... :lol
