CAD Model for smart servos

Lynxmotion Servo Erector Set

Hello, I am trying to change from simple servos to use the LSS as the actuators in an advanced hobby robot I’m building. My robot’s components are mostly 3d printed, and so I need more information on mounting & integrating with the smart servo form factor. I found the mechanical diagrams on the wiki that describe the threaded inserts depths and patterns on the top & bottom of the servo.

However, I’m looking for 2 things: a step/stl model of the servo so that I can integrate it with my 3d printed body. I’ve found these for standard hobby servos, dynamixels, and other smart servos; but I’d really like to use LSS since the LED actually serves an aesthetic purpose, and my output component uses a 24T spline already.

EDIT: I found these https://wiki.lynxmotion.com/info/wiki/lynxmotion/view/servo-erector-set-system/ses-servos/ses-lynxmotion-smart-servo/ . Tiny feedback: It would be nice if the pages that link here included the words “STP”, “STEP”, and/or “STL” for people like me who Ctrl-F for keywords :slight_smile:

The second current thing I’m looking for is photos/examples of how the SES brackets can be used to create a mounting pattern on the sides of the LSS rather than the top/bottom. I haven’t been able to find any photos on lynxmotion.com or RobotShop that show the “primitives” of the connectors.

Thank you for your help!

Hi dsg123456789,

Glad you found the CAD files. (will look if it’s possible to add a stl / step text)
Regarding the brackets, there are two ones that can be used a Single and a Double.

Single does half the servo (1") and double the whole side (2").

Some examples:

Thank you so much! These diagrams are incredibly clear–I wish I could’ve found them easily on the site!

One more question about the LSS–how much axial/shear load do the bearings in it currently handle? I’m going to be pushing a rod with the servo, and I feel like I’ve read mixed signals about how safe it is to push with the horn.

Thank you,
David

We do not have a clear data on the axial load it can handle.
However the output shaft / final gear is one block and supported by two ball bearings, as you can see here:

The new ST1 & HT1 are both full aluminum now, no threaded inserts in plastic casings.

If I ordered an ST1 and HT1 a few days ago, will I be getting the full aluminum models? I’m excited to see these details about the output shaft–I’m crossing my fingers I don’t need to add a pillow block :slight_smile:

I think we ran out of the earlier “plastic” model so you should get the all aluminum ones.
The HS1 however is still plastic.
