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!

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


250 PCS M3x5x4.2 Brass Inserts

It's been a while since I included brass inserts and have had a couple requests recently for more. This time there's 250 pieces. Definitely useful for inserting into prints and bolting parts together.

RGB TIlt Lamp

Download at Printables

I saw this lamp that instead of using a typical on/off switch, you could flip it over and it would turn on and off (did someone link something in Discord? lol) anywho - I thought it was cool and set out to make my own version.


Items included:

  • Ball Tilt Switch
  • 2 x M5 x 10 Bolts
  • 1 Meter RGB LED Strip
  • 1 x 4AAA Battery Pack
  • 3 x F to F Jumper Wires

As usual, the wire ends are what's really needed, some wires will be attached to a single jumper end.

Note: On the LEDs, there is an extra red and white wire, those are "power booster" wire and are not needed.

  1. Program the control board first, scroll down below for instructions on that
  2. If you choose to use the included LED strip adapter wire, then plug it in to the LED strip instead of cutting off the end, or cut off the end =P
  3. Connect the red wire from the battery pack to one of the prongs on the ball switch - you can either solder it directly, or use one of the F ends of a jumper wire. The prong on the ball switch is thinner than a jumper connector, so secure it in place with some electrical tape
  4. Use 2 wires both with a female jumper end on one end and stripped bare on the other (basically cut one of the jumper wires in half and strip) then twist both wires to the red wire on the LED strip.
  5. Connect 1 female end to the ball switch and secure in place, connect the other female end to the VIN on the control board. This will power the control board and the LED strip when the ball is "active"
  6. Connect the black wire from the battery pack, the white wire from the LED strip to a female end of a jumper, secure with electrical tape or shrink tube.
  7. Connect the jumper end of that wire to a GND on the control board
  8. Connect a final female jumper end to the green wire on the LED strip, secure with shrink tube or electrical tape, and plug that into D16 on the control board.

Wiring is complete.

  1. Put the control board into the electronics holder
  2. Put the battery pack (with batteries) into the electronics holder
  3. Fit the end of the electronics holder with the small circle into one of the end caps and secure into place with M5 bolt
  4. Place the ball switch into the small circle on the electronics holder - if it's too loose you may need to secure it in place with some glue/super glue/electrical tape
  5. Place the LED Wrap printed part over all of that, routing the wires of the LED strip  out the slot and press the LED Wrap into place, it should fit into the slot of the end cap.
  6. Wrap the LED Strip around the LED wrap as many times as you can, spacing it out enough so that the end wires go through the slot at the top, there should be plenty of space to shove the extra wires inside. The strips have a sticky side if you remove the blue strip.
  7. Place the Diffuser over all of that and it should fit into the cap around the outside. I tried to make it all one edge but there's still a lowered section to hold it in place.
  8. Place the other cap on top and fit it into everything with the slots and then secure it in place with the other M5 bolt.

It should be working!

WiFi Control Instructions - Programming the board

  1. Connect the ESP32 to your computer via USB
  2. Download esphome-flasher
  3. Download WLED you want the version - WLED_0.x.x_ESP32.bin
  4. Open esphome flasher
  5. Find the bin file you just downloaded for WLED
  6. Click Flash (you may need to hold the boot button on the ESP32 board to flash it)
  7. Go to your phone's App store and install the following app:
    • For Android find WLED by Aircookie
    • For iPhone find WLED Native by Christophe Gagnier
  8. When your control board reboots after being flashed, it enters into Access Point mode, so open up your WiFI on your phone and connect to device WLED-AP, the password should be -> wled1234
  9. After connecting, it "should" open up a page on your phone's browser to enter your home network ID and password, then click save and connect
  10. Open the WLED app on your phone, click the + to serach for and add a device. Once it's connected you can control the light from your phone.
  11. If you get the IP address of the light from your router, you can also access it from your PC or a browser using the IP address.

You can change the pin in the settings of WLED as well as change the number of lights if need be. It defaults to 30 lights and D16 as the pin (it used to default to 4 so originally I stated D4 above)

  1. Hey Josh! Do you have a link to a video of one in action? Is it tilt to turn on/off, does sensor mounting orientation matter? I’m considering using a different model for this project 😁

      Heya Kevin!

      So the ball tilt switch does have to be up and down to work – currently only video of it in action is in discord =P I’m feeling better so planning on making the tutorial video tomorrow. As long as the electronics fit in the other model you’re planning on using, it should work fine and if there isn’t a slot for the ball switch you could just glue it in place =P

    2. The tilt switch is “on” when the pins are down. There are two balls inside that make contact with the pins. Flip it over and the balls move away from the internal contacts, turning it off.
