STINK - available control with XBOX controller

I present You STINK (Small Tank). It is a small tank that uses simple electronics and can be controlled with any sort of bluetooth controller (I was using XBOX controller). It's main board is ESP32 DEV KIT V1 and in the zip file You will find the code for it or in the Other Files.

Below is the list of components necessary:

• 1x Lower Body - PLA
• 1x Cover - PLA
• 2x Front Wheel - PLA or PETG
• 2x Rear Wheel - PLA or PETG
• 44x Tracks - TPU
• 4x Bearing 4x11x4
• 2x M4x25 DIN 912 screw
• 4x M4 nut DIN 985
• 88x M3x8 DIN 912 screw
• 4x M2x5 DIN 912 screw
• 1x ESP32 DEV KIT V1
• 1x PCA9685 servo control board
• 1x Pololu reg09a - step down (any step down board that will get You 5V output
• 2x Servo SG90 (make sure to buy continous variant of this servo)
• Any sort of battery that outputs 7.4V and fits :)
• 8x Magnet fi6x2 mm

Assembly should be very easy but to make sure I'll list the most important steps

1. Take the Lower Body and insert magnets into correct holes.
2. Screw PCA9685 board using two M2x5 DIN 912 screws into Lower Body.
3. Insert two Servo's on both sides and screw them to the Lower Body using screws included to the Servo's.
4. Insert Rear Wheels onto shafts of the Servos and secure them using M2x5 screws.
5. To the front of the Lower Body insert M4x25 screws into the corresponding holes and secure them from the other side with M4 nuts.
6. Insert Bearing into the Front Wheels (two for each wheel).
7. Impose the Front Wheels onto M4x25 screws and secure them with M4 nuts - check the alignment with the Rear Wheels, both wheels should be at the same width. You can add M4 spacers onto M4x25 screws behind Front Wheels to modify the placement of it.
8. Assemble the tracks - one track is made from 22 Tracks and 44 M3x8 screws and put them onto the Wheels. 
9. Insert 4 magnets into Cover.
10. Connect the electronics - SDA and SCL pin on the Servo Control module should be connected to pin D21 and D22 on the ESP32 - the rest is on Your side :)
11. Write the code onto ESP32 board and enjoy :)
