This part is true scale. For the Italeri 1/35th kit, please see the version specially fitted for it.
This part is the Elco 80' PT boat throttle push rod deck housing that runs along the starboard coaming from aft of the forward turret to the aft end of the coaming. All parts are to detailed Elco drawings except for flanges slightly thickened to meet printing minimums. Included are 2 separate end sections, one for a straight sided coaming and one for a coaming with a scale slight taper.
The first step is to clean all parts thoroughly. Handle very carefully as the plastic is brittle. Please see the guide and links here: http://www.pt103.com/3D_Printed_PT_Boat_Parts.html. For best painting results be sure to follow cleaning with a UV cure from a lamp with the correct output, or the sun.
Fit sections together making sure the tapered locating plugs go in without having to use force.
