28BYJ-48 Stepper Motor in OpenSCAD

thingiverse

You're looking to design a custom stepper motor in OpenSCAD, and the 28BYJ-48 is a popular choice due to its affordability and ease of use. To begin, you'll need to install the SCAD library for stepper motors. This can be done by copying and pasting the following code into your OpenSCAD file: `include <BoltLib.scad>` Next, define your motor parameters such as the number of steps per revolution (200 in this case), the motor's dimensions, and the type of shaft it will have. `module 28BYJ48Motor() {` Here is where you can customize the design. You can change the dimensions, add or remove features, or even create a custom mounting system. For example, if you want to add a flange to your motor, you can use the following code: `translate([0, 0, -5]) cylinder(h = 10, r = 12.7, center=true);` This will add a cylindrical flange to the top of your motor. Now that you have defined your motor design, it's time to create the actual stepper motor. This is done using the `translate` and `rotate` functions in OpenSCAD. `translate([0, 0, -10]) rotate([90, 0, 0]) cylinder(h = 20, r = 5, center=true);` This will create a cylindrical body for your stepper motor. Finally, add any additional features you want to your design. You can use the `cylinder` function to create a shaft or the `cube` function to create a base plate. Here's an example of what your complete code might look like: `include <BoltLib.scad>` `module 28BYJ48Motor() {` `translate([0, 0, -5]) cylinder(h = 10, r = 12.7, center=true);` `translate([0, 0, -10]) rotate([90, 0, 0]) cylinder(h = 20, r = 5, center=true);` `cube(size = [20, 20, 10], center=true);` `}` `28BYJ48Motor();`
