The Pololu universal aluminum mounting hub allows you to mount custom wheels and mechanisms to 3 mm motor shafts. The hubs are sold in pairs, and each hub includes one 4-40 set screw for securing a motor shaft to the hub. The set includes one Allen wrench and two 4-40 set screws for securing the hubs to motor shafts. Each hub has four mounting holes for 2-56 screws (not included).
These universal mounting hubs are designed to work with most 3mm shafts, including round shafts, “D” shafts, and Tamiya’s 3mm hexagonal shafts. Each hub has four mounting holes for 2-56 screws (not included), letting you mount custom wheels or mechanisms to your motors. 4-40 hex set screws (one included for each hub) allow secure coupling of shaft to hub. A 0.05″ hex wrench (often the smallest size in SAE Allen wrench sets) is included for use with the set screws.
The picture below shows a hub with one of Pololu’s mini metal gearmotors and a Pololu mini metal gearmotor bracket.
