Ford Truck Door Cup Holder

Recently I rented a Ford Superduty for about 8 weeks. Since it had a 6th seat between the front driver and passenger, there wasn't a place to set my drink with all seatbelts in use. This is my solution to that problem - a cup holder that sits on the door handle. Should fit most recent full-size Ford truck models, confirmed with both my 2018 F350 and my brother’s 2017 F150. Mirroring the file should fit the passenger door too. I recommend printing in PETG or more heat resistant filaments to not risk warping / melting on hot days.
