Makers and RC enthusiasts, this 84-piece pulley set is exactly what you need for all your DIY projects. You get 40 plastic pulleys with 2mm holes in 8 different sizes (from 6mm to 24mm diameter - 5 of each size) plus 44 rubber bands in multiple sizes. This variety means you can tackle almost any mechanical project - RC cars, robots, airplanes, or whatever creative idea you're working on. The 2mm shaft size works with most small motors and axles commonly used in hobby projects. The rubber bands provide the traction needed to transfer power effectively between pulleys. What's really great is having multiple sizes - you can experiment with different gear ratios and configurations to get exactly the performance you want. I've bought smaller sets before and always run out of the size I need most, but with this collection, you're covered for multiple projects. The plastic is durable but easy to modify if needed, and the rubber bands have good stretch without snapping too easily. Whether you're building from scratch or repairing existing models, having this assortment on hand saves multiple trips to the hobby store. The price is fantastic for what you get - individual pulleys can cost much more separately. This is one of those utility sets that every maker should have in their toolbox - you'll be surprised how often you reach for it once you have it available!
