The 12-piece PLA+ structural set for one LeRobot-compatible SO-101 leader arm—the manually moved controller used to demonstrate motion and record training data.
This is the exact individual-file manifest used to prepare the order. The selected controller plate replaces the other plate; it does not add a thirteenth piece.

|---|---|---|
| 1 | Base motor holderBase_motor_holder_SO101.stl | Supports the shoulder-lift motor above the base. |
| 1 | BaseBase_SO101.stl | Forms the lower body of the arm and houses the first joint. |
| 1 | Base motor retainerMotor_holder_SO101_Base.stl | Locks the shoulder-pan motor into the base structure. |
| 1 | Wrist motor holderMotor_holder_SO101_Wrist.stl | Retains the wrist-flex motor at the end of the forearm. |
| 1 | Forearm / under-arm linkUnder_arm_SO101.stl | Connects the elbow joint to the wrist assembly. |

Manifest based on InfiBuild’s pinned production source revision eecbe3e. Gauges, all-in-one reference plates and optional TPU compliant-gripper files are not included.
The leader is moved by the operator to command a follower arm and capture demonstrations. We pin the upstream source revision used for production, print in PLA+, remove supports and visually inspect the set before dispatch.
This is an independent fabrication service compatible with the open-source SO-101 design. InfiBuild is not affiliated with or endorsed by TheRobotStudio or Hugging Face.
The paired set includes both printed structures needed for a leader-and-follower build.
