3D Printable Fixed Iron Sights

So I really needed a pair of Iron sights for my gun, but the previous sights I made ( the folding sights at http://www.thingiverse.com/thing:603954) are really a pain in the ass to get to print properly, mainly because when I designed them, I didn't have a printer... 0 % experience in 3D printing... Soo I designed everything without any tolerances.
I have not abandon the folding sights, but it just takes a while to fix the files I made.

They are designed to work with other commercial iron and reddot sights at a default height of 35 mm from the top of the rails.

As the title says, they are fixed sights, aka nonadjustable.
