This Tainter gate is to be 3D printed in 2 printes. One print for the gate and one for the housing. Crank or rod not included as a wooden dowel would likely be easier than printing. A real Tainter gate has arms but for the sake of 3D printing that area is left solid.
The .dxf and .dwg files are included for modding purposes
It is about 2x2x2.
