This kit includes a set of plywood laser cut centering rings and fins and 3D printed fin supports. This will add to the durability and scale appearance of your Estes Doorknob model kit.
The 3D printed parts are printed using resin material and a SLA printer. It has been processed post printing to remove residual resin and support material. Final finishing is straightforward. Minimal sanding with superfine sandpaper is usually all that is required. If there is residual uncured resin present it should be removed prior to finishing. Wiping the part down with a microfiber cloth soaked with isopropyl alcohol is recommended. Let the part air dry completely before proceeding. Applying a primer is needed before final painting. Tamiya brand primer is strongly recommended. Recommended adhesives are standard epoxies or cyanoacrylate. Epoxies will give the most durable adhesion. Other adhesives will not work and may destroy the print.
