MJX 14211 Non-Destructive Magnetic Car Body

I noticed a magnetic car body modification scheme for the 14303, but it was not compatible with the 14211, so I had to develop one myself.

Changing batteries and detaching the car body becomes significantly more convenient. You also mitigate concerns about damaging the car body in collisions, as it will simply detach upon impact rather than sustaining direct damage. Furthermore, there is no longer a need to repeatedly connect and disconnect the ribbon cable.

This modification scheme is implemented based purely on the original factory configuration, requiring no disassembly of any components on the vehicle. However, the car body will be elevated by more than one centimeter.

For optimal strength, it is recommended to use PETG or PETG-CF for printing.

Components required for purchase include:

                30x 12x4x4 magnets with through holes (ensure they possess opposing polarities for attraction)

                Alternatively, 30x 15x4x4 magnets with through holes may be acquired for enhanced magnetic force

                30x M2.5x8 countersunk screws

                30x M2.5x2x3.5 heat-set inserts

                4x M5x14 countersunk screws

                4x M5 locknuts

                4x O-type crimp terminals (3mm bore diameter)

Two of the M5 mounting plates, featuring grooves, are designed for attachment to the car body posts, while the remaining two, without grooves, are intended for securement directly onto the car body.

Utilize the original R-clips for secure fastening (refer to accompanying images).

Sever the light wires at an appropriate point, then connect the terminal connectors and fasten them onto any two magnets. The identical procedure is applicable to the car body connection.
