This wooden component of the spool mates with the motor coupling connector, which attaches the spool to the motor shaft.
This wooden component of the spool attaches to the opposite end of the spool from the motor. This flange is slightly larger to prevent cable from slipping off the spool.
This wooden component of the spool serves as the winch around which the cable will wrap when spooling and unspooling. Users can find dowels of similar sizes and cut the dowels to the appropriate length.
If the user has access to a 3D printer, they may choose to 3D Print the spool as opposed to fabrication with wood components. It is advised that the user prints the spool standing upright on the solid flange. The user should utilize supports to prevent warping of the material between the flanges.
This wooden component was designed to adapt the original FarmBot Universal Tool Mount to the cable driven system. Through the square shape of the plate, it allows for attachment of all four cables via the swivel hooks at each of the four corners. The square shape also allows for equal weight distribution of the vacuum pump, UTM, and tool heads to each of the four cables. The central hole provides space to route electrical cables and the aluminum extrusion that is used to assemble the vacuum pump, UTM, and camera to the wooden board.
Each of the components for the spool were translated into dimensioned engineering drawings to facilitate fabrication by future users.

L Brackets were used to secure an aluminum extrusion to the wooden plate. The aluminum extrusion serves as a mounting mechanisms for the vacuum pump, vacuum cover, and camera. The UTM is placed beneath the bottom face of the plate and is secured there. A hole has been cut to allow for connection between the vacuum tubes and electric cables to the UTM connectors.
