E3D-Buggy Mini 4WD

Fantastic E3d-Buggy Mini4WD version with led lights

Here's how to transform the fantastic E3D-buggy into a Mini4WD using the components of a mini 4wd. There are 2 different models, one with a rear rack and one without, both are designed for the insertion of led diodes if desired.

PRINTING INSTRUCTIONS:

• MATERIAL: PLA AND FOR THE LIGHT COVERS, A TRANSPARENT PLA IS BETTER
• LAYER HEIGHT: 0,2
• INFILL: 10%
• SUPPORT: YES

I RECOMMEND MANUAL SUPPORTS ONLY IN THE POINTS SHOWN IN THE PHOTOS, BECAUSE IT IS A STRESS TEST THE BRIDGES DO NOT NEED TO BE SUPPORTED

THE SUPPORTS MUST BE PUT ONLY IN THE E3D BUGGY, IN THE CHASSIS AND THE ENGINE SUPPORT IS NOT NEEDED

PRINT THE REST OF THE COMPONENTS POSITIONED AS IN THE PHOTO

REQUIRED COMPONENTS:

If you already own a mini 4wd you will only need a few components, otherwise you will need to buy one for yourself

Components to be taken from a mini4wd :

• 2 wheel axles 

• gears and pivot 

• wheel axle washers

• motor 

ASSEMBLY INSTRUCTIONS:

We prepare the engine mount

take the larger engine mount and gear pin                                     

insert the pin with the help of pliers in the engine support, the pin must be inserted all the way down

take the 2x8 screw and the joint pin and screw it to the motor mount

now let's take the engine and the second engine mount

insert the motor in the hole prepared in the first motor support then insert the second support in the rear part of the motor (the motor contacts must be facing upwards) and finally fix everything with a 2x6 screw

we insert the gear into the pin as shown 

in the photo.

Let's move on to the chassis: let's take the chassis and the wheel axle washers

fit the plastic washers into the

 appropriate holes on the frame

insert the bushings in the rear axle

place the largest gear in the rear right part of the

 frame (pay attention to position it as in the photo)

place the 4x4 transmission gear on the left side of the frame as shown in the photo

take the motor with the support and fit it in its seat, making sure that the gears do not move

insert the rear axle making sure that the 2 gears remain in their position and placing the 2 bushings one on each side so that they fit into the 2 washers

 Fix it to the frame with the 3  2x6 screws

Now let's move on to the front axle

position the second drive gear as shown

repeat the same procedure for the rear axle

take the transmission axis and insert it as indicated in the image, blocking it with the appropriate blocks that you have printed

Lock trasmission bar

snap the two blocks into their pins

LET'S GO TO THE ELECTRICAL PART

TAKE THE BATTERY HOLDER AND POSITION IT SO THAT IT FITS INTO THE PINS PRESENT ON THE BOTTOM OF THE CHASSIS, THEN HEAT THE TIP OF A SCREWDRIVER OR A SCREW AND SQUEEZE THE TWO PINS TO DISSOLVE THEM TO LOCK THE BATTERY HOLDER

MOMENTARILY PLACE THE SWITCH IN ITS PLACE AND CUT THE POSITIVE (RED) CABLE, IT WILL BE SOLDERED INTO THE CENTRAL PIN OF THE SWITCH. WITH THE REMAINING CABLE JUST CUT, WELD IT INTO ONE OF THE 2 REMAINING PINS AND THE OTHER END MUST BE WELDED TO THE ENGINE PIN (TEST BEFORE WELDING THE CABLES TO THE ENGINE SO IT RUNS IN THE RIGHT DIRECTION). RUN THE BLACK LEAD UNDER THE ENGINE AND THEN SOLDER THAT TOO.

REPEAT THE SAME PROCEDURE TO FIX THE SWITCH TO THE FRAME

NOW WITH THE REMAINING SCREWS FIX THE CHASSIS TO THE BUGGY

I RECOMMEND THE LED LIGHTING PART TO THOSE WHO ARE MORE EXPERTS 

AT THE END IT'S TIME TO START RUNNING AFTER YOUR BUGGY AND TO HAVE FUN WITH FRIENDS IN ACCELLER RACES.
ENJOY CHANGING THE VARIOUS ENGINES WITH MORE POWERFUL OTHERS AND CREATING ALL THE MODELS OF RIMS AND WHEELS YOU WANT, ACCESSORIES ETC.. HAPPY PRINTING
