Salt Shaker - *vibrating*

prusaprinters

<p>Hi<br/> This is a small salt shaker with a vibrating motor of an old cellphone in it. When you turn it upside down, a metal ball will connect the circuit connecting the two button cells and the spinning morot will vibrate dispence the salt.</p> <p>To be honest. Its a fun gadged and everybody using the salt is irritated. But the output of the salt is not that hard controlled / increased by the vribration.</p> <p>Check Print instructions to see printing and electrical inputs.</p> <p>Greetings</p> <h3>Print instructions</h3><p>Hi</p> <p>at first the printing instructions:</p> <p>in general make 2 outer perimeters and some infill of ca 20% to have a strong material for the screws going directly into the plastic. Layer height sould be around 0.16. I used a 0.4 mm nozzle when designing the thing. So i would recommend the same. But 0.3 will work as well.</p> <ol> <li><p>Print "Gehäuse11111" from bottom up. No support needed. I created some support pillars. These pillars needs to be removed with a cutter.</p> </li> <li><p>Print " Gehäuse2222" from bottom up. No support needed.</p> </li> <li><p>Print "Gehäuse33333" from top up to avoid the use of support.</p> </li> </ol> <p>Assemble instructions:</p> <p>Top Screw: M3 x 10 torx (head diameter: 5,4mm)<br/> Side Screw: 3x M3 x 10 torx (head diameter: 5,4mm)<br/> The thread is going direct into the plastic. Do not tighten the screw too much.</p> <p>Electronic instructions:</p> <p>Motor: vibrating motor from an old cell phone. (usually easy to disassemble) Size: Diameter: 10mm height: 3mm<br/> Botton cells: 2x AG13/LR44 1,5 v each Diameter: 12 height: 5<br/> I used as "wires" some thin nickle stripe as seen on the picture.<br/> The metal ball connecting the circuit needs to be ca 7mm in diameter.<br/> I used a resistor to decrease the rpm of the vibrator a bit. But thats not neccesary.</p>
