The STL files are in 1/200 scale (in mm units).
The final object height is 6.24 mm (0.245 in) for the bigger one, 3.7 mm (0.145 in) for the smaller one
N.B. There are very tiny parts, a resin printer is highly recommended.
For any difficult or question I am always available to give you assistance.
I would be very grateful if any of my models could help you to do a great job.
