Sphero

Supplement your Blueprint Build Kit or Class Pack with Blueprint Pulley Packs. Pulleys are precision-crafted wheels with grooved rims for seamless operation with ropes, offering a shift in force direction or creating mechanical advantage (MA). Available in 30mm, 45mm, and 90mm sizes, these pulleys add versatility to your builds according to their specific needs. The 90mm Pulley, equipped with a locking shaft insert for stronger rotational forces, can also be transformed into a vehicle wheel by adding the Tire. For simplified use, insert a Lock or Bearing Plate into the 30mm or 45mm Pulley, adjusting the shaft through the center.Compatible With Blueprint Build
