86 base_plate length of a side, it is a square
3 base_thickness low 2s, I raised to 3mm for strength
75 duct_flange_base_top_OD_diameter outside diameter of duct flange at base plate at top of base plate
70 duct_flange_base_bottom_ID_diameter inside diameter at the bottom of base plate, the taper goes to the bottom of the plate, there is no perpendicular segment within the base plate
70 duct_flex_diameter
43 duct_flange_total_height includes base and adds 1mm since I measued 42, but I'm increasing base by 1mm to 3mm
73 duct_flange_top_outside_diameter
