I recently picked up a Steiner Military 3-12x50 rifle scope and was searching around for a sun shade. Long Story Short: I cant find a factory sunshade (in stock) so I'm going to make a custom one. Ill get photos of my progress later today.
 
I measured the outside diameter of the scope so I can get a baseline for how large this shade is going to be. Im making a slip over shade design (much like the Buttler Creek scope caps). The outside diameter is ~2.274"

my material of choice is Carbon Fiber Fabric using an epoxy/resin binder. (because it looks cool and is super light weight)

good news and badnews...
Bad News: had to cut a relief in the fabric because stupid me forgot that the epoxy shrinks more than the aluminum does and it got stuck on there.
Good News: It is fixable, since this isn"t a load bearing object I cleaned it up and wrapped another layer of fabric over it making it look 100x better.
you're probably thinking "what the hell is this kid doing?" quite frankly I don't even know. Ive done some carbon fiber work before and had good results. EX:

how much shrinkage do you get?
is it they type of epoxy you use or something else
I didn't measure the shrinkage but normally with my other CF projects it takes some effort but the product normally pops right off nice and clean. Since this a thinner product I didnt want to force it and have an uneven break/ crack (similar to the end shown in the picture) so I decided to make a "straight" cut relief and it popped right off. The carbon fabric and epoxy I buy from a guy not far from me. https://carbonkevlarsupply.com/

Doesn’t effect it one bit. I cut a slit the size of a 22 shell in a fabric and put over the end with a rubber band and that was just as usable

I did the fabric one on a 3.5-10 Sightron SIII and could use on 3.5 to 10 without any issues.
