Human: Creating a rotating lithophane cube. Uses 100mm x75mm 3mm thick lithophanes. A 2.1mm border is made using resources found at http://3dp.rocks/lithophane/. The inspiration for this project came from ChrisN219's Instructable, located at https://www.instructables.com/id/Rotating-Lithophane-Box/#discuss. I was dissatisfied with the clock mechanism, as it lacked sufficient power to rotate the cube effectively. After trying it out, I realized that a small motor would be more suitable for this purpose. The price of the small motor is comparable to the original clock mechanism, and its torque is adequate for rotating the cube. The basic concept remains the same, but I revamped many aspects of the design to suit my needs. A small DC gearmotor is used for motion, secured in place by an M3 socket head cap screw. Power from the LED power supply is spliced into the motor circuit. An inline switch controls the motor's power, and magnets are pressed into the pockets, ensuring correct orientation (polarity) before installation. To set the height, I employed an M3 cap screw with a jam nut. The capscrew adapter is inserted into the receiver in the center stud of the cube's top. Four different screw cap adapters are included: one without a center hex fitment and three others with a hex key in the middle, each featuring a slight step down in size. I recommend printing all three in PETG to determine which one fits your screw best. Additional components include a WiFi module (available at https://www.amazon.com/gp/product/B07QG7HCZG/ref=ppx_yo_dt_b_asin_title_o01_s01?ie=UTF8&psc=1) and a strip light (located at https://www.amazon.com/gp/product/B00KQHQJ5C/ref=ppx_yo_dt_b_asin_title_o01_s01?ie=UTF8&psc=1). Any 4x2mm neodymium magnets can be sourced from Amazon or eBay.
