I will be adding some assembly details soon but I wanted to get the files up.
Use the base, inserts and hardware from this design to make the base for the tower: https://www.printables.com/model/719725-110-scale-rc-car-stand
I used the power supply mount from here: https://www.printables.com/model/742075-custom-parts-for-chad_35259-car-stand with this power supply: https://a.co/d/f4MKTBj but you can also use a 12v power supply and the universal mounts from my car stand and then you don't need to step the voltage down.
Use this charger: https://a.co/d/j2qWzkF
This voltage regulator for USB and lights: https://a.co/d/2ogOlp6
