Arduino Soap/Sanitizer Dispenser

So the goal here was to build a Soap/Sanitizer without using the "servo motor method" instead go with another approach, which is "CNC LINEAR RAIL BASED STERILIZER FLUID DISPENSER" in order to make a LOW COST DIY Sanitizer dispenser to fight against covid19.

i designed everything in fusion360 and then 3D printed it and added components like stepper motor, driver, ultrasonic sensors etc.

this is actually pretty straightforward built,

first, you need to print these parts and gather all the electronics components that we need.

Parts that you need to 3D print for CNC rail -

1. END x1

2. Motor End x1

for rest of the built

3. Upper x1

4. LOWER x1

5. Lid x1

6. backbone bracket x1

7. Front support x1

8. back support x1

9. base x1 (or just use any plywood as the base)

for the CNC rail built instruction, watch this video

(I've just changed the carriage of the linear rail with a different one which has two holes on it for attaching the lever )
