Sticky Note Spin Art Machine

thingiverse

This is a rebuild of a project I hacked together with hot glue, bottle caps, and cardboard back in high school. I used to take it babysitting and kids went wild. Stick a post it note to the top plate, tuck the corners in, attach the motor leads to a power source and switch and you're ready to paint! To build this, you need to print one of the spinner tops, a motor shaft coupling, and a motor mount. More details (part list, dimensions) in Instructions. Instructions All parts print without support. My print: FlashForge Creator Pro ABS, 230C Heated bed, Blue Tape Electronic Parts List DC Motor (found in a box in the shop, could not find part no. online) Batteries Switch Battery Holder (sometimes includes switch) Wires My Build: Nichibo 232022 DC Motor 4 AAA battery holder with switch (Radio Shack) 4 AAA batteries 2 jumper wires 6 x 6" board to attach motor mount 4 wood screws Cardboard box to contain flying paint Motor Mount Dimensions: ID: 1.13" Height of motor holding section: 1.4" Shaft Coupling Dimensions: ID: .13" Assembly: Using Top_002, press the shaft coupling into the mating hole on the back of the spinning top piece. Add a drop of superglue if it isn't a press fit. Attach jumpers to the two leads of the DC motor. Thread through the holes in the motor mount. Insert motor into motor mount housing. If there is significant clearance, wrap electrical tape around the motor until there is a snug fit. Extra vibration will make the assembly noisy. If you are going to mount the motor mount to something (advised) do so now. You can tape it onto the bottom of a box, use screws, bolts, zip ties... again, more vibration will be noisier in use. Once the motor is secure, press the shaft coupling onto the DC motor shaft. This should be a snug fit, as you want the coupling to move with the shaft. Now that the spinner assembly is complete, run the wires out to your power and switch. Make sure this is far enough away from the spinner that you can turn it off without putting your hand in the path of the spinner. If you are containing the whole assembly in a box, it's nice to put the switch outside of the box. If you haven't yet, put the assembly in a box or surround it with walls of newspaper. Paint flying off the spinner will paint a nice line on anything exposed in the vicinity. If everything is secure, turn it on! The spinner should run without excessive vibration or noise. If it sounds terrible, make sure it's balanced and everything is secure. When the spinner is off, load a sticky note into the top, turn it on (with hands clear) and drip paint onto the surface of the note. After I think I've done enough, I like to let it run for another 30 seconds to dry before I turn it off and remove the mini art.
