Crazy gearbox 10:1

thingiverse

I am absolutely captivated by the compact dimensions of a nema17 motor, measuring in at 31mm and out at 42mm. This tiny size makes it an ideal candidate for gearbox production - I can hardly believe how well-suited it is to this application. It's simply brilliant that this motor can be paired with a variety of Bowden materials, offering compatibility on multiple levels. Its efficiency in operation is also noteworthy, making it a top choice for those seeking reliable performance. This concept revolves around the innovative use of Pulley and Rubber band technology - a true marvel of design. The proposed material options include plastic or aluminium, both of which offer durability and flexibility. The gearbox features 1x pulley input, 1x pulley output, and an impressive 4x pulley stages, all held together with 5 rubber bands measuring less than 3mm in length. A single bearing 625zz adds stability to the design. With a ratio of 1.51:1 for one stage, this gearbox boasts a total ratio of 8:1 when fully assembled - a remarkable achievement! The dimensions of the gearbox are equally impressive, measuring 44x44x26 in size. I would love to hear your thoughts on this ingenious design - do you have any opinions or suggestions? It's definitely a fun and exciting concept to explore further.
