Ultimate Scale Upgrade Kit for Estes Doorknob


If you are interested in the ultimate scale upgrade to the Estes Doorknob kit, this is for you!  It includes the 3D printed fin can (which has the fins supports and the vent holes seen on the prototype), 3D printed scale launch guides, 3D printed fins and laser cut plywood centering rings.

These parts are printed using resin material and a SLA printer.  They have 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.
