Description
DIY Motorized Roller Blind System
This is a simple and practical 3D printable motorized roller blind system designed for DIY makers, electronics hobbyists, and 3D printing enthusiasts.
The system is designed to manually control a roller blind using a 12V DC geared motor, powered by a 3.7V 18650 Li-ion battery. The battery voltage is boosted to 12V through a Type-C Li-ion charging and DC-DC step-up module. Direction control is handled with a 6-pin ON-OFF-ON rocker switch, allowing forward, stop, and reverse movement.
This project is intended as a simple low-cost DIY solution for motorizing a small roller blind or similar rotating mechanism.
FEATURES

COMPONENTS USED
DC Geared Motor
Model: JGB37-520 DC12V 319 RPM
Operating Voltage: 12V
Speed: 319 RPM
Current Draw: 140 +/- 40 mA
Load Torque: 1.14 kg-cm
Stall Torque: 4.5 kg-cm
Shaft: 6 mm D-shaft
Rocker Switch
Model: KCD4 ON-OFF-ON
Type: 6-pin rocker switch
Function: Manual forward / stop / reverse control
Size: 35 x 25 mm
Battery
Type: 18650 Li-ion battery
Voltage: 3.7V
Capacity: 2200 mAh
Discharge Rate: 5C
Charging and Boost Module
Type: USB Type-C Li-ion charging and DC-DC step-up module
Battery Input: 1 x 3.7V 18650 Li-ion
Output: Adjustable DC output
Output used in this project: 12V
Cables
2 x female-to-male jumper wires
Approx. 10 cm motor power cable
POWER FLOW
18650 Battery 3.7V -> Type-C Charging and Step-Up Module -> 12V Output -> DC Geared Motor
This allows a single 18650 battery to power the 12V motor through the boost converter.
3D PRINTING NOTES
Recommended print settings:
Material: PLA, PETG, or ABS
Layer Height: 0.20 mm
Wall Count: 3 walls or more
Infill: 25-40%
Nozzle: 0.4 mm
Supports: Depends on the part orientation
For stronger mechanical parts, PETG or ABS is recommended. PLA can also be used for testing and light-duty applications.
IMPORTANT NOTES
- This is a DIY project and may require basic electronics knowledge.
- Motor direction and wiring should be checked carefully before use.
- Make sure the boost module is adjusted to 12V output before connecting the motor.
- Battery protection and safe charging practices are recommended.
- Component dimensions may vary slightly depending on the supplier.
- The STL files may need small adjustments depending on your exact motor, switch, and module dimensions.
- Electronics are not included. This download contains only the 3D printable STL files.
