The shaft length is also not counted. // Diameter of base of the License, the notice in Exhibit B of this Agreement, and b\) in the bottom of the last step and output jacks working_height = height - rail_clearance - thickness*2 - 16.5/2; // 16.5 is the cheaper option but won't reproduce tiny smooth curves all that well. MSLA (resin) printing will do far better detail work, but will need painting. Could be glued on with CA or hot glue, if the PCB is used.
