## Bill of Materials
|
|
|
|
### Servo
|
|
|
|
Servo is the key component. I use TowerPro [MG92B](http://www.towerpro.com.tw/product/mg92b/). It has metal gear (important!).
|
|
An hexapod requires 18 of them.
|
|
|
|
Note.
|
|
The dimension of 3d printed part is highly depended on servo's dimension.
|
|
Modification is required if you want to use other alternative servo.
|
|
|
|
Note.
|
|
TowerPro MG92B can be found on Ebay seller [servohorns959](https://www.ebay.com/usr/servohorns959), which is listed on TowerPro official website ([Link](http://www.towerpro.com.tw/about-us-2/)). I also got mime servo from him.
