Mechanical Dancing Articulated Crab "Crazy Legs"

prusaprinters

<h3>Edit: revised “ring Lock” clearance</h3><h3><strong>“Crazy Legs” </strong>The Dancing Mechanical Crab</h3><p>&nbsp; &nbsp; &nbsp;This is an articulated Crab that Dances (Moves it's Legs) when you move the lever in the back left and right. This model was harder than my last “mechanical” model. &nbsp;Lot's of patience and filament later whala.</p><h4>Printing</h4><p>SCALE IT DOWN AT YOUR OWN RISK</p><p>&nbsp; &nbsp; &nbsp;I printed this model in PLA with standard 0.2 layer height prusaslicer settings. There is ONE part, the (RingLock) that needs supports (sorry). &nbsp;The included the G-Code file has the support already set up and the 3MF file (for prusaslicer) also has the necessary support included. &nbsp;The STL file needs support on the outer overhang only. Some of the pins I made to snap the pieces together are fragile but they will do the job.</p><h4>Assembly</h4><p>&nbsp; &nbsp; &nbsp;In order for the 8 rear legs to move properly you must follow the directions.</p><figure class="image image_resized" style="width:75%;"><img src="https://media.printables.com/media/prints/294220/rich_content/a7368640-4081-4d90-a82c-737e532c79bb/ba41a980-2958-4c78-ae40-08cf4d504ec4.jpeg#%7B%22uuid%22%3A%22082a40c6-fef1-4f24-af09-7773982faf9a%22%2C%22w%22%3A3024%2C%22h%22%3A4032%7D"></figure><p>Place the “bottom&amp;legs” piece flat on a surface making sure the levers on the inside of the legs are pointed straight up (pictured below)</p><figure class="image image_resized" style="width:75%;"><img src="https://media.printables.com/media/prints/294220/rich_content/142e2007-131d-4708-8814-a18920703226/e7dbd15f-57da-423e-9f88-9f5e6f29c33c.jpeg#%7B%22uuid%22%3A%22a79bf30a-df2e-4572-98ce-bdf905b69a97%22%2C%22w%22%3A3024%2C%22h%22%3A4032%7D"></figure><p>Next, push the “ring” into the groove on the bottom (This will push down on some of the pins)</p><figure class="image image_resized" style="width:75%;"><img src="https://media.printables.com/media/prints/294220/rich_content/e31fffdf-a953-4a49-ace5-f96eff3d4709/f445cbfc-d740-4e45-8fbd-2123a62d99f2.jpeg#%7B%22uuid%22%3A%22d70cd02e-3a36-4209-9607-961cfc0276f8%22%2C%22w%22%3A3024%2C%22h%22%3A4032%7D"></figure><p>Next, insert the “arm drive” and “rear drive” gears in place. &nbsp;The lever on the rear gear should be to the left.
