Engine Model 60% scale version

Note: This model is not compatible with Kit 005, please see below for materials

This is a miniature, meticulously crafted engine model.

I have scaled down the engine model to 60% and adjusted some of the parts.

The scaled-down engine is slightly more difficult to print and assemble and requires some patience.

BOM:

• M1.7x5 Flat Tail Self-tapping screws

• D2.5xH1.0 Magnets *4
• D2.5xH2.0 Magnets *5
• D2.5xH3.0 Magnets *4
• D2.5xH5.0 Magnets *3

• 0.3xD4.0xH5.0 Springs *4

  Please choose a spring with a diameter of 4 millimeters and a length of 5-8 millimeters.

If you would like to install a motor, you will also need the following parts:

• N20 motor 6V 190rpm

• M1.4x12 Hexagon socket screws *2
• M1.4xΦ2.3xL3 Hot melt nut *2

Notes

• To achieve better printing results, I used a 0.08mm layer height and enabled ironing. If not required, please modify accordingly.

• Some parts are very fragile after being scaled down, and need to be pre-drilled with a Φ1.6 drill bit before carefully screwing in the screws. Direct screwing can easily cause breakage. It is recommended to print several spares of such parts.

  

• This part is prone to printing failure, it is recommended to apply glue to the printing plate and try several times. I have a success rate of around 50%. If it cannot be successfully printed, the threaded part can be cut off and fixed with glue.

  

• If you do not intend to install a motor, please delete the USB type-c opening.

  

• Installing the motor requires embedding two M1.4 hot melt nuts. If you do not intend to use hot melt nuts, please reduce the diameter of the mounting holes.

  

• I have adjusted the placement of the heat sink for better printing results. It has been tested that it can be successfully printed using a Bambu polished printing plate with glue. If printing fails, try lowering the printing speed.

  

• The magnets are very small, so it is recommended to use N52 grade magnets to ensure that the lid is securely installed.

• Below are the installation locations for all magnets. To maximize magnetic strength, I have used magnets of various sizes. If you are replacing magnets with other specifications, please adjust the sizes yourself.
