50mm Rifle scope iris cover
thingiverse
I quickly whipped up a remix from a great model, to try as an iris-style 50mm riflescope protector. Scope with 50mm front optics has 60mm outer diameter casing, so the protector will fit on a tube that has same diameter. Recoil is not an issue here as i am using the scope in a PCP air rifle. I will post pictures and info how it went, the model is still printing as i type. update: The iris does not work as well as i expected - i have trouble with the pins holding up. The scope ring works fine though.
