gChart's Machine Made Class, 9th Annual BLF/OL contest

Well, I was originally thinking I’d enter in the Hand Made division again, but I’m switching it up and going with Machine Made.

My original thought for the housing was to use a steel canister to do a tin can punch lantern. I still think that’d be cool, but I’ve never done it before and I seem to have less time than ever (full time worker, father of five young kids, on several committees/organizations, etc).

So… I’ve decided to let a machine do some of the work for me. My 3D printer that is. Enter Exhibit A, the main components and tools for my entry:

  • Wemos D1 Mini
  • NeoPixel 16-LED ring
  • Ender 3 Pro with filament

Busy weekend working on the light (of sorts).

First off, a clip of the first piece being printed:

And here’s the end result of that:

With the middle section complete, time to design the top and bottom pieces using Fusion 360:

And here’s a shot of that lower section being “sliced” in Cura (taking the 3D model and turning it into 3D printer instruction code):

Here’s a shot of that top cap being printed:

The first iteration of the base being printed. Notice the organically looking structure in that middle. Those are “tree supports” that give overhang something to print onto. You can’t just print in mid air!

And, well, I didn’t get a couple pieces of the design perfect on the first try. So back to Fusion 360 for a couple adjustments, and back to the printer. This time I used a more “normal” support structure of lines. The original print of the base took 18 hours. I didn’t want to wait that long for the revision so I greatly increased the speeds and played with the support structure settings to get it down to 6 hours. What a difference some of the settings came make. Generally speed comes at the expense of quality, but it worked out fine for this model.

So… the physical pieces of this light are pretty much done. I’ll show off a bit more of it later. It’s time to move onto software/firmware!

Awesome, gchart.
Can’t wait to watch the next “episodes” of your flashlight build.
