I recently acquired a 3D printer, specifically to use for my hobby interests. One of those interests is scratch building rockets. This is my first (flyable) rocket off of the printer, a downscale version of Derrick Deville's QU8K rocket. The QU8K is 8" in dia. and flew on a "Q" motor to 121,000ft agl in serach of the Carmack Prize. My downscale is based on the nominal BT-60 airframe, and utilizes a 24mm motor mount to fly on "The Mighty D" as well as the Aerotech RMS 24/40 and 24/60 motors.
This rocket was initially designed in SoldWorks 2018, and sliced in Cura 3.6.0. The printer is a Creality CR-10S. The printed parts are printed with a PETG Filament, as PETG has excellent strength and heat properties (won't melt as easy as PLA filament). The body and motor tubes came in a Flis Kits Builder Extravaganza kit.
The Components:
Hints:
For best results, the fin can was printed with supports, as a number of prints had issues with sagging material at the trailing edge of the fins. The fin can is mostly wall construction, except for the integral launch lug. This print was sliced with 50% infil using "Lines" as the patern.
The nosecone is also mostly a wall construction, and many of the thicker parts like the base, and the last 3" of the nose are sliced with a 50% infill using the same Lines pattern.
The coupler, baffle and upper rail lug are printed with 100% infill, as they serve as recovery attachment points, where I want as much strength as PETG filament has to offer.
Should you wish to build your own QU8K model, all of the files can be found at Thingiverse using this link:
