Scope Anti Reflection Devices. You could probably scale in the XY plane as needed to fit yours if these are not the right size. Measurements are based on the OD of the scope as these are meant to slip over the scope.

Note: I tested this with heavy recoil and the ARD will fall off, I'm not sure how to resolve this...maybe coating with rosin or some other tacky non marring material will help or scaling the part down to fit tighter. I thought about adding loopholes to allow for use of the stock cover elastic cords...might do that at some point in the future unless I find a better alternative.

Resolution:

Infill:

Filament: Generic TPU Black

Notes:

My first time printing with TPU, reduced retraction and slow printing speeds help as TPU has the consistency of cooked spaghetti. I was able to get my bowden extruder to print TPU reliably by slowing down to under 30mm/s

I do not think this design will work with anything other than flexible filaments. If you try to use a hard material layer separation is likely. Category: Sport & Outdoors
