The files which are not available are not required for the servo brackets. Those parts are a place holder for the servo only. You do not need to print them.

@Rich: how to attach these two files? to make it work...

Take the back off your servo (remember they are made to fit ez robot servos) and replace the back of the servo with this part P23 A-01.STL.... Then the second part attaches to the servo output shaft and also to the first part you just installed....

i want to edit the STL file because im gonna use this servo

http://www.servodatabase.com/servo/towerpro/mg996r

but i dont how to edit... if there is a good heart willing to help just to fit the MG996 servo i will appreciate it...

thx

To download all the stl files:

1. Open ARC
2. Click on the project tab
3. Click on design
4. Select servos from the drop down list
5. Then when the list is populated you will see an information icon under a shopping cart. Click the information icon
6. You will see each printable file that makes up the part along with a save stl button for each file
7. Save the stl file to your computer
8. Print/modify the stl file to suit

On the website only 3D-Printable parts allow you to download the stl files.

I recommend using our servos with the designed brackets since they are sure to fit, they are the same price, stronger and will operate at 7.4V unless you have already bought the towerpro mg996r servos :)

Heavy Duty Servo

I modified the files to fit some Futaba and HiTec servos I have. Looking at the picture and specs of the servos you bought, the files I loaded here should work for you as well: https://synthiam.com/Community/Questions/7066
