This is an eyepiece I made for a Vortex Venom scope. The fitment diameter is about 44mm but it should be fairly easy to scale down. It works as intended to reduce glare from between the shooters eye and the scope. This is my first TPU project and I don't know one from another. I used Overture TPU which turns out to have more of a vinyl feel, like vinyl pool liner, than rubbery. I'm new to all this and created it in Tinkercad. if someone remixes it in a more capable CAD program and likes their result, please notify me.
