Threaded inserts and magnets were done post printing. I used PETG for most of the parts. Used CA glue to join major parts. I went through three iterations and I wanted to recover some of the magnets to reuse, no way, I was flabbergasted how well the glue held the magnets and parts together and the PETG was almost indestructible. (printed with 3 walls and 25% infill.
Will be interesting to see how the cheapo pistol lasers perform ($17 each). I did look down the metal tube (like a gun barrel) and the dot was perfectly centered but a tad high, which I would expect with the laser mounted to the top of the tube.
The calibration will be a bit tedious, I'll use a surface plate and a Starrett master level, and a construction laser as a reference.
I figure it will work much like using a string for alignment, but referenced off the rim bead profile and not the tire.
I'll be making another one (single laser) so both sides of the car can be checked at the same time.
