Rifle target frame hardware

my local range requires the use of personal target frames... rather than building one using metal hardware, pvc pipe, and other stuff... I designed hardware that allows the frame to be repaired, and with the largest piece of hardware being a wood screw,,, (it takes about 64 screws) I would suggest PETG for printing.

my frame is 7 feet tall with a 3x3 foot base. I would recommend using sandbags if you are out on a windy day.

besides plastic, you will need some 1x2 (nominal, 3/4" x 1.5") boards... (available at your local hardware store in the US... you will also need some wood screws (either 1/8" - 3/4" long or m4 x 18mm)... Our range requires the frame to be 84" high... Wood size: 2x 84" long, 2x 12" long, and 3x 36" long.
