2/28/2024 0 Comments Automata black box model 3dAttach the crank assembly from the outside. Place the “Drive Bevel” inside the base against the hole in the side wall, ensuring that the teeth are properly meshed with the larger bevel gear. To find the right orientation, align the ridge on the posts of the “Spinning Terrain” and “Cam Support and Bevel Gear” and position the cams such that the lowest point of the cam coincides with the borrow that the bunnies dive under. Push the “Outer Bunny Cam” and “Inner Bunny Cam” on to the “Cam Support and Bevel Gear.” In order to achieve proper timing of movement, the cams must be placed on the cam support in the proper orientation. Place the “grip pin” through the hole in the “crank” and secure it in place with the “grip.” The grip should be able to spin freely on the crank. Lubricate any moving surfaces with Vaseline prior to assembly.Īssemble the crank. The critical bit of cleanup here is that the “followers” slide perfectly through the guides in the “lid.” If there is either too much friction or too much slack the machine will jam. The hex attachment also prints best when oriented upwards. When removed, the tree supports leave a nice textured “ground” surface. The “Spinning Terrain” prints best upside-down with tree supports. Print one of each of the remaining files.Ĭarefully remove any burrs or imperfections in the print especially on surfaces that move against one another. The model shown has six in each ring for a total of twelve. Print as many of the “Follower (Thin Neck)” and “Bunny” files as you want. This automata is an entry into the Spring 2022 Thangs #MakerMadness design competition. The attached pictures also show the automata in various stages of assembly. The only difference is that this bunny automata has a modular cam assembly. This assembly video ( ) is for a similar cam-based kinetic sculpture. You’ll need good knowledge of optimal print settings for your machine and the skills and tools to do some post-print processing. See here for a video of the automata in action: All the bunnies must dive into the burrow at exactly the right time or they’ll bang their little bunny heads! The outer ring of bunnies jumps three times while bunnies in the inner ring jump only two times. I started with just two bunnies and then look what happened!
