Simple Pulley (Simple Machines)

thingiverse

I'm working with my third-grade students on simple machines in school. To take it further, I've decided to design and 3D print our own using Fusion 360. When choosing the material, I suggest opting for PETG over PLA for increased strength when lifting heavier loads. To save time, each part should be printed individually. The only piece that needs to be printed twice is called "Support 2". Fortunately, supports are not required. The printing settings are as follows: Layer thickness of 0.2mm, no supports needed, infill at 50% or higher for added strength, and perimeters set to 4 with a width of 0.8mm. Once the parts are printed and assembled using glue, we can use a string with a hook to lift the load and secure it in place with another string or hook to a higher position. If you decide to print this, please share your project with us!
