Tabletop Tri-Mode Spring Motor Rolling Chassis

Tabletop Tri-Mode Spring Motor Rolling Chassis Elevates My Previous Designs with "Pull Back Windup" Mode. This latest creation builds upon my earlier spring motor designs, introducing a third mode: "pull back windup". While it may not outperform its predecessors in terms of distance, this compact vehicle adds the "pull back windup" mode to the power and true coast modes found in my previous floating pinion designs (check out dual-mode-windup-car at youmagine.com and dual-mode-spring-motor-rolling-chassis at youmagine.com). My earlier designs leveraged a single floating pinion, dubbed "Drive Pinion", which enabled the vehicle to truly coast by disengaging the rear axle from the spring motor. However, they required a knob or key to wind the spring. This new design incorporates a second floating pinion, labeled "Wind Pinion", which facilitates winding the spring through rapid reverse rolling of the vehicle, eliminating the need for knobs or keys. Watch a prototype in action at this link: . To bring this creation to life, you'll need to procure 12 AS 568 size 221 o-rings (1 7/16 O.D., 1 11/16 I.D., 1/8" diameter) for the tires. Please note that I may have overlooked a few files, so don't hesitate to ask if you have any questions. This design was crafted using Fusion 360 and sliced with Cura 2.3.1 before being printed in PLA on an Ultimaker 3 Extended.
