This is an blender addon which can create motor. We parameterized many features of a motor and so user can generate various model in same type but different parameters.
There is an extended version of this Addon blenderMotorFactory2.0.

Requirement:
- This addon only support blender version 2.90.1. Other version may cause unpredictable falier.
- Blender Bolt Factory should be enabled. It is a default addon in blender, you can enable it in Edit > Preference > Install > Add Mesh: Bolt Factory.
- Download the project
- Clone project via
git clone https://github.com/cold-soda-jay/blenderMotorFactory.git, then pack folder src into a zip file or - Download zip file from realese.
- Clone project via
- In Blender, go Edit > Preference > Install and find the zip file. After installing make sure it is activated.
- Now you can find the Addon in Add >Mesh >Motor
This Addon allow user generate various model and save the parameter as well as model as .stl file. To save the model, you can run the command in blender Console (Shift + F4 to open it):
bpy.ops.mesh.add_motor(save_path="Path of folder")
The model will be saved as a whole entity and seperate parts
When you modified some motor manually and want to save the model and property value part by part, you can choose Save the model and then give the loaction where you want to save the model. Then the model you created will be saved.
The parameters of generated model will be saved into a csv file when save_path setted. Every model will be saved in a separate folder with a number as name. This number represent the Id of the model. The parameters of this model can be found in csv file.
The position of all bolts will also be saved as a list in the file. The order of bolt position is from bottom to top. See picture below for more details.
Top Type A with extension 2.
Top Type B with extension 1.
Every bolt will have a vector to store its position and orientation. In CSV the last colum stores all bolts positions. The result is a [3*2*n] list. Each bolt position will be represented as a vector [ Top_position(x,y,z), Bottom_position(x,y,z) ].
E.g.: [ #Bolt 1 [ [x1,y1,z1], [x2,y2,z2] ], #Bolt 2 [ [x3,y3,z3], [x4,y4,z4] ], ..... ]
To generate more models at once, you can use script ./src/auto_generate.py. In the script you can set the number of generated models and define several parameters when generating. Here are all parameters:

After setting the parameters, you can run the script in command line with following command:
path/of/blender -b -P path/of/auto_generate.py 1> nul
