Still new to 3D modeling but tried my best to make a display mount for my ducks. Keeps them from sliding around. There is a model for 1, 2, 3 or 4 ducks.

I recommend printing in PETG since they will probably see the extremes of heat/cold depending on where you live. I added slits inspired by the iconic Jeep grill so they wont block the defroster. Fits most ducks but if the hole on the bottom is small you might have cut it open a bit to fit.
