Moveable Rifle Rest

I find that I lean things against the edge my basement work bench (boat paddles, pellet rifles, curtain rods, florescent light bulbs, etc..) constantly. They are always an accident waiting to happen and after knocking a rifle over and screwing up a scope mount last weekend, I decided to do something about it. I designed a movable rifle rest that can slide in the t-track on the edge of my bench so it can be positioned anywhere I need it, out of the way, or taken off completely with the flick of just two levers.

I printed it in really high resolution with 60% infill, which took forever, but I feel that it looks great and will last years, silently doing its job of not letting me screw more stuff up. the opening is over an inch to fit a wide verity of things and I will be gluing in a piece of felt or cork to keep from marring anything.
