3D Printed Fin Set for Estes Doorknob

$69.00 

This is a set of four 3D printed Doorknob fins that replace the fins included in the kit and are designed to work with plywood centering rings.  The leading edge taper is included in the print, along with the internal tab.  

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.
