2 door Jeep Back Seat holder

Often I keep the back seat of my 2 door jeep wrangler JL in the upright position to give me more room for groceries.  This is a simple plug that fits in the locking park of the legs and I use a 12" bungie cable attached to a D ring on the jeep and the end of the plug to jeep the seat from bouncing up and down as I drive.

I've printed it in both PLA and Petg, but I would recommend Petg for the heat resistance.
