very easy to print, no need supports. Just rafts on the knob if you see adhesion is not enough.
You got STL of inferior base, superior base, rotating plate and knob for the tension regulator.
Put the battery on the seat, and the motoreducer with n°2 M3 screws. Connect battery and motoreducer to the tension regulator adn put it on his seat.
**** I also added a simple support to use as a background. Put an A4 or A3 sheet and create your own photo studio
