Description
PDFA variation of our rocket engine sample model with added side nozzles. It's printable completely without supports.
If you own the Original Prusa MK4S, CORE One, or CORE One L printer, you'll find pre-sliced version of this model on the USB drive. This model is also featured on the box your MK4S came in.
Serves as a nice example of the different print volume sizes of these three printers.
There are two versions of the 3MF file, the MK4S version is slightly different (it has a little embossed “MK4S” on it; both the CORE One versions are plain).
