Human: I needed a rotating display stand for a printout of this ambiguous cylinder:http://www.thingiverse.com/thing:1668263\nI searched Amazon and didn't like anything I found, so I quickly created this in Tinkercad and added an Arduino Nano and a cheap 9g servo to it. It's working pretty well so far. The cheap servo I included does almost 180 degrees. That's close enough for what I'm doing here.\nVideo of it actually working is here:https://www.youtube.com/watch?v=SnhmS1U0bKQ\nPrint Settings\nPrinter Brand: Printrbot\nPrinter: Simple Black\nRafts: No\nSupports: No\nResolution: .3mm\nInfill: 10%\nNotes: Quality doesn't matter much on this print. For one, it's not the thing on display, and for two, the thing will print a lot faster at larger layer heights. There's no fine detail to capture, so that's okay.\nPost-Printing\nPrint, tape, wire, glue. Print out both pieces. I added black duct tape on the surface of the rotating disc piece to keep things from sliding off.\nThe wiring diagram is attached as an image. Pieces are hotglued into the structure. See photos.\nParts:\narduo nano - $6ish on Amazon, but you can find them for 2-3 bucks a piece if you're willing to buy a dozen or so from Aliexpress/Ebay.http://smile.amazon.com/ATmega328P-Microcontroller-Board-Cable-Arduino/dp/B00NLAMS9C/\n9g servo - $3ish each on Amazon if you buy 5:http://smile.amazon.com/Genuine-Helicopter-Airplane-controls-TowerPro/dp/B019H9BNTQ/\nOther than that, it's just wires. I added a 5V boost converter and put plugs on all the connections because I like reusing my parts from old projects and it's easier if they have plugs. You could wire this with a lot less wire if wire management is your thing. I'm terrible about leaving too much wire in things.\nThe code is up at:https://github.com/bobiam/rotobox\nIt's a slight modification of the sweep program. My servos aren't quite getting 180 degrees, but they're close enough for my purposes.\nHow I Designed This\nBuilt in Tinkercad, with source files available here:\nhttp://www.tinkercad.com/things/cDHnetI0y6V-rotoboxbasehttp://www.tinkercad.com/things/cfv2FyRuqTN-rotoboxlid
