Doorknob Scale Fin Can Scale Upgrade for Estes Kit


A one piece 3D printed scale fin can for the Doorknob kit.  It features 12 scale openings and fin supports featured on the prototype, replacing the black decals featured on the kit.  Compatible with the balsa fins and cardboard centering rings featured in the kit or our upgraded laser cut plywood fins and centering rings.

This part is 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.
