This is a decorative mini radial aircraft engine with a rotating propeller that's easy to print! (NO SUPPORTS REQUIRED).

The model is printed entirely in separate pieces, without the need for AMS or a similar system.

There are no complicated assembly instructions; the parts fit together easily and intuitively. The only necessary components are:A 605 bearing for smooth propeller rotation and your preferred glue for securing the parts.

NOTE 1: The propeller blades are printed in two parts:A larger, single-color part, and a smaller, colored tip for the blades. This smaller part requires filament changes, but you can easily print it without AMS using manual filament changes, as I did myself (my printer is a basic model without a multicolor support).

NOTE 2: The front grille of the engine, which has the shaft for attaching the bearing, has one hole in the center. This hole was made so that you can insert a piece of filament or metal pin with glue so that the shaft where the bearing is attached does not break in any way.

NOTE 3: The mounting base and the bottom part of the mini motor fuselage have 3 holes. In the three holes of the base, you should glue 3 pieces of filament; they will serve as pins for you to fit the motor assembly. The pins are glued only to the holes in the base, so you can remove the mini motor from the base whenever you want and then reattach it. The fit is firm and precise.It is possible to attach the mini motor assembly to the base in two ways, as can be seen in the model images:With the assembly slightly tilted upwards, or straight, parallel to the table. In both ways, the fit is perfect and firm.
