December 2023 UFO

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!

Congrats to ....
for winning the December 2023 Mothership Box!

This month, the Mothership prize is still to be determined - am waiting to hear back from a couple companies, but it will be a 3D Printer - question is which one =P

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

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


328 Pcs Heat Shrink Wire Tube

I use these a lot whether working on 3D Printers, extending wires, or joining wires on electronics projects. Quick and easy step slipping these onto the wires where they are joined and applying heat to shrink and seal them down.

+Nano version of the UFOs received an ESP32-WROOM

Dragon Fog Lamp

Kit Includes:

• Ultrasonic Fogger with LEDs - View on Amazon
• Power Adapter
• 3oz Clear Cup (Optional if you don't want to print the dragon egg)

This is a water holding project, so you'll need to use printing methods to get it as water tight as possible to prevent leaking. These are my suggestions:

Print in PETG (PLA can absorb the water after a while and expand)
Print settings I used in mine: 4 Walls, 4 Top Layers, 50mm/s, Low Fan, 240C print temp

If you still have leaking issues, the cheapest way I think to seal is to get a cheap candle, melt it down and line the inside with a thin layer of wax. Epoxy works good as well, and I believe there are some sprays that can be used to seal.

Dragon Egg: I printed in PLA with 2 walls, zero bottom layers, zero infill. There's a setting in PrusaSlicer, I can't remember which (ensure vertical shell thickness?) that fills in the gaps at the top of the egg

In the link below the zip contains 2 versions, a plain version and a version with a dragon design.

Note: After running it for a couple days with either the egg or the cup, there was a lot of water being shot out the space between them and the base. I added a splash guard that so far has eliminated the rogue spurts without messing with the amount of fog released.
