<p>Hello</p><p>this is an electric turntable with servo motor and LED backlight. The purpose for me is 3D scanning with skanect sensor. I tested a 15Kg object (my kid) and it worked.&nbsp;</p><figure class="media"><oembed url="https://www.youtube.com/watch?v=2ayovucN8I4"></oembed></figure><h5>Print volume:</h5><p>230 x 200 x 30 for the bottom part.<br>So This basically fills the complete MK3s platen</p><h5>Standard Parts BOM:</h5><p>As usually I just picket parts I had around. Hope this is not too specific.</p><ul><li>Big bearing: 2809 standard outer dia. 22mm bearing (1x)</li><li>Small bearing outer dia. 16mm (4x)</li><li>toggle switch (2x)</li><li>Servo motor (manipulated running as notmal +-DC) 24x10mm body size</li><li>potentiometer (optional)</li><li>8x LED red 2V (8x) (optional)</li><li>M3 screw 10mm with socket screw head (3x)</li><li>M5 screw &gt;16mm flat screw head</li></ul><h5>Build Instructions:</h5><p>Print bottom table part case and pins (4x)&nbsp;<br>Assemble the small bearing with the pins<br>Solder cable to servo and switch and assemble these.<br>(Optional put potentiometer and 2way switch istead for an additional RPM speed)<br>(Optional put switch and LEDs in place and solder them)</p><p>Print Turntable Plate and Shell<br>Assemble the big bearing with a M5 screw and the shell to the plate.<br>The shell is to fit the bearing to the M5 Screw<br>(Optional to avoid shine throught of LED, paint bottom side)</p><p>Print gear and assemble to servo.</p><p>Print Cap and assemble to bottom case with 3x M3x10 screw.</p><h5>General things:</h5><p>The weakest and hopfully first part to break when overloading is the pin.<br>When you print the table with high fill density then this should be quite stable.<br>The surface of the plate where the small bearings are in contact probably needs to be sanded.<br>I used 3.6v Li-Ion battery to power this up. (see my other models)</p><p>&nbsp;</p>
