## CAD

The STEP files of every part are in the product repository, the reference for anything that has to fit:

- [STEPS](https://github.com/Source-Robotics/SSG-48-adaptive-electric-gripper/tree/main/STEPS): the body parts
  (`Gripper STEP files`), the whole gripper (`3D MODEL`), the jaw plate template, the pinch jaws, the generic
  coupler connector template and the UR5 adapter plate.
- [Gripper STL parts](https://github.com/Source-Robotics/SSG-48-adaptive-electric-gripper/tree/main/Gripper%20STL%20parts):
  the printable parts of both hardware versions and the coupler connectors for PAROL6 and PAR6.
- [gripper jaws](https://github.com/Source-Robotics/SSG-48-adaptive-electric-gripper/tree/main/gripper%20jaws):
  the fin-ray fingers and their jaw plate.

## For simulation

The product repository's [ssg48_description](https://github.com/Source-Robotics/SSG-48-adaptive-electric-gripper/tree/main/ssg48_description)
guide links the gripper's models, which are kept in [robot_descriptions](https://github.com/Source-Robotics/robot_descriptions):
standalone URDF and MJCF (MuJoCo) packages of the gripper with solid or fin-ray jaws, with their meshes, collision
shapes and mass properties, and the PAROL6 and PAR6 models with the gripper mounted.

[CAD and downloads](https://docs.source-robotics.com/SSG48-gripper-docs/2/cad-files/) lists everything that can be downloaded.
