body is done. at 8x, the side mirrors will fall off if you look at them the wrong way. they should really be separate parts that are glued on. printing it would be easier, too; for this print I used supports touching the plate (not the body) and yet I still got body rash (seen under the mirror, vertical line on door).
for the wheels, I printed them in black PLA and sunk them into the build plate to chop off their axles. that left a hole, which I could enlarge and force a brass #2-56 3/4" screw. it won't spin, but it will stay and that's good enough for this build
brass was easy to just cut the head off and then either put the all-thread into the body first or the wheel first. don't matter.
wheels were 45 minutes to print, each. again, slow printing and my ender-3 is not the fastest thing in the world. for a $199 printer, I don't complain much about it.
that line under the mirror is really annoying. I may have to take this in to tesla service ... but there's no VIN for this car, so I'm not sure how to add it to my app.
