This housing set is designed to attach to the roll bar of the Axial SCX10 II 1955 Ford F100. This main part needs 3 of the hinge retainers printed. They can be attached with a 1mm pin and then have the retaining hole on the main housing cleaned with a 2.5mm drill bit. Once cleaned, an M3 bottom tap can be used to tap the hole for the 6 mm M3 machine screw. The lenses need to be printed in a clear material. We suggest a resin printer. This is all clearly covered in the video below.
