CVT demo game

thingiverse

This showcases the fundamental concept of a CVT (continuously variable transmission), where two people take on the roles of motors coupled by a differential gear assembly. When the wheels turn at identical rates, the dial remains stationary. Conversely, if one person rotates faster, the dial swings towards the other person. Instructions Nylon gears were created for durability. PLA was chosen for the worm gear due to its low overhang and precise threading. It is printed independently from the 'cradle' housing the differential gears and bonded together using super-glue. ABS was used to create a durable base, wheels, and shafts. Except for the worm gear, PLA was utilized for the cradle, dial, and other components. They could potentially be fabricated entirely from ABS. Heat-riveting attached handles to the wheels, while super-glue affixed wheels to shafts; a drop of glue secured vertical gears, although it's not strictly necessary. The horizontal gear and dial are encapsulated and require no adhesion. Areas for improvement include: To convert this into an engaging game, there needs to be some sort of winner indicator when the dial reaches a specific point. Currently, the dial merely hits supports, risking damage if forced further.
