This is a toy model of an existing NH3 system. All measurements were approximated.
Use light supports. For smaller printers the model may need to be rotated by 45 degrees on the z axis to fit onto the build plate.
Remove support material.
Sand if required.
Measurements were taken by stepping them out and using educated approximations. NH3 plants come in many sizes so this is acceptable in this case. The measurements were imported into tinkercad and millimeters were used as the scale. Your slicer may attempt to default to inches. The total length should approximately be 9 3/8" from tank ends in order to be to 1/64 scale.
