Sun shade for rifle scope

Sun shade for 50mm Scope. 57mm scope O.D. 66mm overall O.D. No mounting hardware needed, should be close to interference fit.

The relief cut is for my CZ452, but i have included the non-relief version to just slip on.

EDIT: I made a 30mm version. but i didnt have a 30mm scope to measure the tube diameter. the internal diameter is set at 30.75mm. in order to find the x and y (printed standing up) scaling factor (i wouldnt change the Z scale) find the diameter of you rifle tube and divide by 30.75 and move the decimal 2 places to the right.

Ex: 30mm exactly tube diameter, 30/30.75 ~ .9756, x100= 97.56% scaling factor
Ex2: if you want to use the 50mm tube on the same scope (30mm) the math would look like this 30/57= .5263x100= 52.63%
