While Instructables contributor, NespLab, a.k.a. Matias Mamone, proclaimed in the introduction of his 3D-printed rotary clock project page that he was neither “a designer or an engineer,” it’s pretty clear that this humble maker is tech savvy. There’s a kind of steampunk aesthetic to his 3D-printed, triple-rotor clock and, for someone who claims to be something of a novice, Mamone’s detailed instructions and his process itself are reassuringly clear and easy to follow.
That said, this project requires some skill or at least a willingness to tackle some fairly complex steps. It also requires a fairly lengthy list of tools and supplies. Before undertaking this project, you will need to have the following tools on hand:
– Something with which to cut metal, like a rotary tool. If you have a handy friend, this might be something you want to borrow as you’ll only be using it a couple of times.
– A 3D printer. This isn’t an absolute necessity as you probably know you can use a web-based 3D printing service like i.materialise or Shapeways. To find a 3D printer near you, you can also use 3D Hubs.
– A computer. At this point, who doesn’t have one?
– A soldering iron. Why not purchase one? Chances are that if you enjoy this project, you’ll take on other projects that will require the use of a soldering gun. You can find inexpensive ones online.
You’ll also need to prepare by collecting the following supplies:
– All of the 3D-printed parts.
– A small stepper motor.
– An Arduino Mini (or Nano, or something similar).
– 1 EasyDriver (or other stepper motor driver).
– An RTC. Here’s one from our friends at Adafruit: DS1307 RTC.
– 280x6mm (at least) aluminum tube, 7”, 6mm diameter.
– 14 M3x8mm screws.
– 8 M3x10mm screws.
The final item on Mamone’s list you won’t find online. You’ll need, he quips “TONS of patience.” You also may want to have some acrylic paint and a brush on hand in case you want to paint the letters of your clock. He used red acrylic paint on black PLA. Speaking of PLA, Mamone printed all of the 3D-printed parts for this clock using 230g PLA at 10 to 15% infill and 0.2mm height. Printing did not require a support or raft layers. He provide the .stl files for all of the 3D-printed parts. In his instructions for printing, he also notes which parts may either require extra measures, including enlarging holes that may not print cleanly.
With this project, you’ll also need to be prepared to, as we noted earlier, do some basic soldering and cutting of metal. Additionally, you’ll be wiring the electronics, programming the Arduino and, of course, assembling everything to create your rotary clock. If at some point you feel, if not despairing, frustrated, dig out that last item on the tools and supplies list: patience. Also know that until you complete the project, nobody is keeping track of how much time you invest in this cool little clock.
