  2. The article itself says what you need to know: "The trade-off is that the final shape of the model is usually imperfect. The average 3D scanner may sometimes struggle with shiny, transparent, or black surfaces, but with photogrammetry the number of artifacts and amount of noise you inevitably have to deal with is vastly greater. The result is, ultimately, a model with high-definition texture, but also a lot of noise and imperfect geometry." If you can't get literally hundreds of clear photos from every possible angle, don't bother. Even if you can, the results will be all bumpy and imperfect. If you want a good quality print, the best way to start with the model is modeling software, not photogrammetry. Even the really expensive, commercial grade scanners, spit out bumpy models that then need to be worked on for hours to make them look good or print well.

    Pine Grove Circuit

    SSD changers usually don't respond well to less than 11v, if at all. The only way to trigger them is with a car being powered by the SSD power base track so that emits the digital signal from the LED which will tell the LC flipper to switch or straighten. If you're not using a controller, then it will only tell the flipper to straighten. There aren't a whole lot of wires to mess with, though. Two for each solenoid, and two to the track to get power.
  4. 1/32 size Wire Wheel suitable for Ninco Classic slot cars https://www.printables.com/model/176018 This model makes use of multi-part modeling and disabling the “clip multi-part objects” option in PrusaSlicer to force each spoke to be printed across the perimeters of the other parts of the wheel for secure adhesion at both ends. While the spokes and knock-offs are not the exact same as OEM Ninco Classic wheels, the rim and rib sizes are the same, so will take a tire made to fit those wheels. The hub will probably need to be carefully reamed, or a THWACK mallet can be used to knock the axle into the wheel. Careful not to ream it too big, or it will be wobbly! The spokes are designed with a .4x.4mm cross section, which is two layers using a standard .4mm nozzle and standard .2mm layer thickness. I cannot speak to how well this will print using other nozzle sizes or layer thicknesses. My prints pictured are proof of concept. It's likely that they can be made better with better quality filament and some settings tweaking, especially for flow and speed while printing the spokes. I did not include STL files because of the nature of these models and the required settings in the slicer to make them print properly.
