October 2023 UFO

Be sure to bookmark a3d.fyi for quick access to UFO reveal posts.

Filamentcolors.xyz is a digital catalog of filament from around the globe, curated with the purpose of helping people find the perfect colors for their project. We print and photograph every filament under the same conditions, allowing users to compare different colors directly. We also measure the color and report this as a hex color, and use that to calculate complementary colors, similar filaments, and even similar colors in other materials to help users perfectly plan their projects. We’re a hobby project and always growing through filament donations and partnerships, so keep checking back to find your favorite filaments!

Congrats to Bob Sch.
for winning the October 2023 Mothership Box!

This month, the Mothership prize is a Diamondback Nozzle.


  • Straw Candy (Sorry I misread when ordering, I thought they were candy straws - not candy powder filled tiny straws >.<)
  • Trading Cards

Subscriber @tsiolkovsky created a neat trading card holder for the top of the printer to hold the card for the sample you're printing with!

Filament Samples

All filament samples are at least 20 meters in length (actually more, I increased the length to eat up the extra filament being left behind on the rolls)

Those looking for a sample spooler, MadMonkey designed this one and it's been my favorite so far https://www.printables.com/model/36621-expandable-sample-spool-holder

DSK has also made a sample spool specifically to fit the samples from the new machine: https://www.printables.com/model/428314-sample-spool-snap


EverBrite Flashlight

Accessories for this month were last minute finds as the stuff I ordered didn't arrive in time due to the Holidays in China so I got something that was in budget - hopefully you'll find it useful!


+Nano version of the UFOs received an ESP32-WROOM

Barilla Passive Cooking Device

This was supposed to be for November since it involves cooking but well... Chinese Holidays... lol

The Arduino BLE's were way too expensive to include as the control board, so the awesome DSK modified the files again to fit the ESP32-WROOM's that I include in the boxes. If you want to use the original Arduino BLE you can find them here.

When you go to the Barilla Passive Cooking page, be sure to click on the "Device" tab and it will have a PDF file with instructions and link to the code.

If you're using the ESP32 board, the code below I've switched to pin 14

Kit Includes:

  • Glass Bead Thermistor
  • Slide Switch
  • Resistor
  • Capacitor
  • 4 x 3.2mm Magnets
  • Nylon Ribbon
  • Battery Pack
  • High Temp Silicone Wire
  • 2Mx8 Screw

Programming the ESP32-WROOM Boards:

There are 2 ways you can program the board.

Arduino Web Editor:

One way is to use the Arduino web editor. You can create a project in the online editor and copy the code into it. Just follow the websites directions on getting the needed plug in installed. The board you would select is the esp32 dev module

Locally on PC:

First you will need the Arduino IDE installed on your computer. Which you can install from 
https://www.arduino.cc/en/software . If you are using windows 11 I would suggest to download and install the legacy IDE version as new one gets some access denied errors.

Once the IDE is up and running you will need to install the esp32 board.

First thing you will need is to install the Espressif esp32 board library. You can do so by following the tutorial on the website below: [Note for our board select the esp32 dev board]


After the board is installed you can open up the .ino file for the project.

You can the select the board Esp32 Dev Module and the correct port and click upload.

This should compile the code and send it to the board for you!
