Cat treat dispenser
thingiverse
This is an Archimedes screw-like mechanism that can dispense cat treats, among other things. Here is the [onshape link](https://cad.onshape.com/documents/0c03c5c5149025bc83e8267d/w/14a9466621494e3156ec90d7/e/c708a279b39a02c037e91f48 "Cat treat dispenser | Onshape") ###Assembly put the screw inside the chassis, putting the round hole in the screw to the peg in the chassis. **There are holes on both sides of the screw, but one has a flat part and the other is a circle. Make sure you are using the right hole!** Then put the base on the chassis with the holes on the bottom of the chassis. finally, put the top on the chassis by matching the shorter pegs to the cutouts in the chassis. ###Operation You can either use a NEMA-17 size stepper motor or the included hand crank. Either way, you should be able to connect it to the top of the screw. I plan on using an adafruit nRF52832 and stepper motor wing to dispense a cat treat over Bluetooth. I will leave a link to that code here once it is done.
