STLs include the center mount, bottom mount, and side mounts for standard V-shaped LED channels. I apologize I am writing these instructions from memory and do not have build photos. Please message me with any questions.

Print instructions:

Prints are fairly simple I just placed a flat side on the build plate and oriented the opening in the sphere to the side or facing up. Supports required. I have printed in PLA and PETG. If using white I would suggest PETG because the PLA I used becomes discolored over time with exposure to ambient uv. Remove all supports including within the center mount sphere and the bottom mount wire hole.

Parts LIst:

• Printed Parts

• XL thumb tacks or screws (see instructions)

• LED strips of your choice (must be 3 wire max). I used 5V WS2812b, 60 LEDs/m, No waterproof coatings necessary unless you live in a particularly humid area.

• LED V-channel (milky white diffuser is best but not strictly necessary). Slight variations in dimensions should work fine.

• 3-5 meter length wire (measure from the top ceiling corner straight down and to the intended outlet). Try to minimize the length for data integrity and to minimize voltage drop. I used white cable to blend in with the wall

• LED controller and a power supply appropriate for the number of LEDs and type of LED strip (useful link in instructions)

Assembly instructions:

The light is assembled by wiring the LED strips in the v-channels with data starting at the center mount for all three. It is necessary to create a 3 way split for the LED wiring to ensure each leg of the triad matches. Before final assembly create a 3 line splitter using 2x JST connectors and leaving one lead as bare wire. Use the minimum wire length you can in the splitter because all of the wiring needs to cram into the center mount.

The 'data in' leg of the splitter should be a 3-5 meter long run of wire. This wire will run from the center mount (ensure the center mount is oriented properly when inserting the splitter) through the hole in the bottom v-channel and out the lower end of the channel. It will then route into the hole of the bottom mount channel slot (ensure the data line of the LED strip is pointing downward). Use an appropriate gauge wire for the total number of LEDs. You will most likely need to separate the wires to fit them through the hole. Take out the slack in the wire so that the bottom mount is flush on the bottom V-channel. Solder the bare wire piece of the splitter to the bottom V-channel LED strip ensuring the LED strip data is point away from the center mount.

Final assembly happens piece by piece, on the wall. The center mount with bottom channel is mounted first oriented properly to line up with the placement of the 3x LED channels. I used XL thumb tacks to mount all of the mounts, but the holes could easily be enlarged for screws within the slicer. Fasten the center and bottom mounts to the wall with chosen fasteners. 

Note: the slots in the mounts for the v-channels are left with some wiggle room intentionally to account for imperfectly angled walls. 

Solder JST connectors onto the remaining 2x LED strip V-channels (use opposite male/female connectors as are used for the splitter). Ensure you solder the connectors at the data in end of the LED strip. Use the minimum length of wire possible because all of the wiring needs to cram into the center mount. With the center mount and lower channel already mounted, insert each side channel by connecting the JST connectors and inserting the end of the channel into the center mount. Be careful not to damage the solder joint, I would suggest adding some hot glue to the joint for strength. Then add the final two mounts to hold the other end of the side V-channels. That is it for the light side of things. Now onto the controller/power.

You can use any off the shelf controller for the LED strip you chose but I would recommend a WLED controller or a pixelblaze controller for maximum control and effect quality. Add fuses to the wiring as appropriate. This website is helpful for finding power/fuse/wire gauge requirements based on total pixels and type of LED strip: [https://wled-calculator.github.io/](https://wled-calculator.github.io/)

Connect a JST connector to the power end of the 3-5 m wire and connect to your controller/power. For this number of LEDs it is best to avoid running power through the controller.
