MK4 Rocket Engine - Threaded Remix

No one likes when a print fails hours into it after already printing the "easy part!" This remix is for anyone that’s afraid of (print) failure or wants an easy way to 2-color print the MK4 Rocket Engine without manually swapping filament mid-print. It allows the rocket's nozzle to be printed separately from the rest of the engine & then be easily assembled into one model. Or, if you want the ability to swap nozzles on your rocket engine (say, for a multicolored one down the road), then this remix is for you!

To build this threaded remix of the MK4 Rocket Engine, you will need to print one of each file. Once both parts have been printed, just simply thread them together!

Print Settings

All parts should be properly oriented & are designed to be printed without supports. For best results, print using a 0.2 mm layer height. I used 15% infill, but you can experiment with other infill densities if you’d like.

How I Designed This

Using Vlado Turek’s .3mf file as a starting point, all remixing was done in Fusion 360.

This threaded version of the MK4 Rocket Engine was remixed from the original Rocket Engine - MK4 sample model by Vlado Turek (Prusa Research).
