At the request of a friend, I created a prank car/truck hitch extension, fits standard 2 inch hitch, printed a quick display unit from PLA but i would suggest PETG to handle the elements. Tried out tree supports for the first time and they worked incredibly well, The profile is for the A1 in PLA, but you may want to take the raw file and create your own preferred print profile. Sneak this on your friends vehicle and have a laugh. Bottom part in photo is covered but a good breeze will reveal a set of gonads. Enjoy and make some one laugh.
