REV 12v Battery Spacer for REV Expansion Hub

thingiverse

Our robotics team positions two REV Expansion Hubs horizontally in parallel along the robot's central axis, secured to two 15mm REV extrusions. This arrangement leaves a 30mm space between the hubs, which is precisely the right size for our REV 12v battery. The battery must be mounted on its short end to fit snugly, resulting in a taller configuration than the expansion hubs. This setup also creates some space at both ends of the expansion hub. To prevent the battery from sliding around, we designed a spacer with screw holes on both sides that connect securely to the expansion hubs. The spacer is perfectly sized to keep everything firmly in place.
