Be sure to bookmark for quick access to UFO reveal posts. 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!

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

DSK has also made a sample spool specifically to fit the samples from the new machine:


10pcs 0.35mm Nozzle Needles

Sometimes we get those nasty clogs, and sometimes we need to poke around in the nozzle

Fume Extractor

120mm Kirby
120mm Extractor Options

Super simple project this month that I hope y'all will find useful. Sliverbaer suggested this project in discord and I thought it was cute.

Linked above is to the Kirby remix, but also a link to a search as there's a lot of 120mm fume extractor STL files available so you can choose which one you prefer.

Items in box:

  • 120x25mm 12v Fan
  • USB Power cord with on/off switch
  • 120x120mm carbon filter

Simply cut the connector off the fan, strip the wires, connect the red to red and black to black and plug it in!

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 . 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!
