Hi, this is Nyanyan.
I did it!
I used this software: Design Spark Mechanical
This 3DCAD software is not so good because the number of the kinds of files which it can import is not so many, but other points, it’s a good free software.
coord.e, who makes YamaX’s software, told me that Sketch Up is better, but I am used to use this, so I used it.
I made everything in this model, included the servo, nut, bolt, etc.
Now, look at these pictures!
Thank you for reading!
