I dont know all the features available in F360, but maybe you could make the bent shape first, then cut out anything that isnt the real body using the side profile sketch. I tried to show what I mean in freecad:

1. make bent shape

2. make sketch that will cut out from the big bent extruded shape (the rectangle on the outside will make the real body left afterwards).

3. do a “cut” or “subtract” extrusion or whatever it’s called in f360

For the imminent CA law about criminalizing some degree of mere speech about 3D2A, would that apply to anyone not in CA? Maybe CA politicians/prosecutors would try to apply it to people in other states, maybe saying that they helped aid a crime in CA or whatever, but I’m not sure if that’s even feasibly enforceable (yet).

Ardupilot Rover has a camera gimbal feature that might make for a good turret controller, if anyone’s interested in those kinds of UGVs: https://ardupilot.org/rover/docs/common-cameras-and-gimbals.html

Im not sure if you mean to specifically clone this design of UGV, but if you are interested in more generally any UGV capable of mounting a yeeter on it, then theres a huge number of videos and tutorials on ones that use lower-impact things like airsoft, paintball, or nerf blasters. Plenty of the designs could be altered if necessary too to handle something with more recoil.
