Carpenter Bee Trap Screw Bottle Flange

The carpenter bee trap screw bottle flange attaches to the standard 4x4 carpenter bee trap (as shown in the pictures) and allows 20 oz and 2 liter bottles to be used to hold the captured carpenter bees. The design was printed on a Anet A8 3D printer. After the flange is printed, use a 20 oz bottle to smooth the threads by screwing the bottle in and out of the threads until the threading action is smooth.
