3D-Printed Shredder
This fully 3D-printed shredder can easily devour a head of lettuce, but needs to avoid plastic objects. It was modeled after its real-life counterpart, the ones that can crush full-sized cars, but shrinks it down enough to be powered by a brushed 775 DC motor, paired with a gearbox to step down its output for torque.



Let’s just say that it easily handles all types of things including paper, red bell peppers, some rotten fruit, and even a McDonald’s cheeseburger. As mentioned previously, it is not powerful enough to handle plastics, metal, or just any harder objects, as it causes the gears to grind before coming to a halt. For those interested, ‘Let’s Print’ used ERYONE Dual Color Series Matte PLA 1.75mm filament to create this shredder.
