“Crazy Legs” The Dancing Mechanical Crab
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. Lot's of patience and filament later whala.
Printing
SCALE IT DOWN AT YOUR OWN RISK
I printed this model in PLA with standard 0.2 layer height prusaslicer settings. There is ONE part, the (RingLock) that needs supports (sorry). The included the G-Code file has the support already set up and the 3MF file (for prusaslicer) also has the necessary support included. 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.
Assembly
In order for the 8 rear legs to move properly you must follow the directions.
Place the “bottom&legs” piece flat on a surface making sure the levers on the inside of the legs are pointed straight up (pictured below)
Next, push the “ring” into the groove on the bottom (This will push down on some of the pins)
Next, insert the “arm drive” and “rear drive” gears in place. The lever on the rear gear should be to the left. Spin it with some downward pressure to make sure it rotates in the slot.
Now line up the “Ring Lock” over the tabs and push down. depending on your filament choice and printer tolerances, this may be tight which is good because it keeps downward pressure on the ring gear. (Be careful not to press on the fragile pins)
Slide the lever on the gear back and forth a few times to make sure it moves freely. (the legs will bounce around)
Take the Arms and move the gears back and forth to free them up. , then put them in the top position as pictured
Align the arm holes with the pins on the ring lock and gently snap it in place. You may have to wiggle the rear gear lever to line up the gears.
The dome is the last and easiest part. it should line up and snap on.
If you have any problems with this model, please message or comment to let me know so I can try to fix any problems. Hope to see some makes!
