This doozy of a 3D print is not for the faint of heart. Inspired by actual commercial jet engines and crafted by the talented designers at 3D Design Services by MakerBot, the Jet Engine makes a great tool for learning about engineering and the possibilities of 3D printing. Get to know how engines work on a whole new level as you assemble the 40+ pieces of this complex 3D print into a mechanical model with actual moving parts. If you need a visual aid for explaining engineering concepts like air intake, compression, combustion, and thrust, or if you just want a fun 3D printing and prototyping project that looks great on your desk, download and 3D print the Jet Engine today. Given the complexity of the Jet Engine, we recommend this print for more experienced 3D print enthusiasts. And take your time when assembling. Remember: glue and patience go a long way! All pieces print without support.
