These v-groove bearing pulleys fit on an M3 x 16mm Hex Cap Screw and can be mounted directly onto extrusion. Use with 15mm Linear Motion Kits and a high tensile strength no-stretch string, such as kevlar string or spectra fishing line, to create an elevator.

Custom hinge system used to create compact, simple hinges using REV 15mm Extrusion. Hinges come in left, right, and center pieces, and are attached together using standard M3 hardware.

Aluminum servo horn that is compatible with the REV Smart Robot Servo. Lightweight but strong, for use under high and low torque applications. The holes on this horn are all tapped M3, and feature patterns compatible with the "4 hole" pattern common in FTC parts, and the new REV hex hole pattern.

The REV Servo Shaft Adapter makes it possible to drive a 5mm hex shaft with any 25T output servo including the REV Smart Robot Servo. The adapter attaches to the servo spline like any common servo horn and accepts a 5mm hex shaft on the opposite end.

The REV Robotics Servo Gear Adapter is a 15 Tooth Plastic Gear that attaches to any 25T output servo including the REV Smart Robot Servo.
