3D printed Servo coupler without modding your servo
« on: September 30, 2018, 11:53:24 AM »
Hi I did not feel like modding my servo to attach this type of coupler


so I designed this coupler so you can 3d print and attach it to the little disc that comes with a servo when you buy it.
 keep in mind its 3d printed and might not be as strong overtime and you need to keep an eye on your coupler everytime you fly my guess.

i did not include the holes in the servo-sided-part since I saw from 2 different servo's both disc's where different in where the holes were so you have to drill the 2 holes with a 2mm /1,5mm drill while marking your coupler and your disc nicely aligned on top of it.






hope this was usefull for someone. The STL for the coupler is in the attachment

PS you should use those mini hex bolts that go intirely inside the coupler to lock the threaded rod in place i just could not find mine and wanted to know the strength.

ms2k,
Thank you for your contribution. It is very appreciated. I hope it works fine when all is completed.
I don't understand this quote: "i just could not find mine and wanted to know the strength".

Thank you victor i just hope it helps people to get cheaper away with building it and you dont have to mod the servo. The M2 bolts were to long that hold the threaded rod in place and you need to use shorter ones else you will hit the inner arms corners. see picture


i have a box of them but I could not find it at the time. and i wanted to test the strength of the coupler but i can tell now since ive tested it and used it that it works fine its also a little shorter then the cnc coupler so i lowered my servo and was able to puter copper tape like thick spongy tape between gps and servo giving no interference.

well the whole drone is 3d printed.. im not sure if "very dangerous" is the thing to call it its just a extra thing to have in mind.. and you dont have to print PLA you can use nylon or ABS for this part. making it a thing less to worrie about but I did add that people should check the coupler each flight if u use this part

beside all that can happen if it breaks is that you wont be able to lower or lift your arms.
