3D-Printed Electronic Snowflakes using WS2811 LED Strip

Instructions

are in the PDF document and in the YouTube video 

Printing the branches

The snowflake consists of SIX branches. A branch is contained in the Snowflake.stl STL model and in the Snowflake.3mf 3MF file. Print SIX copies of the branch. I would highly recommend using PETG rather than PLA as the snowflake will last longer if you use it outside, as I do.

Printing the center

I added the “Snowflake Center.stl” file to Printables. However, you can replace the center by a standard PVC pipe, with an outside diameter of 70 millimeters, if you have one. PVC might be sturdier than PETG.

Assembling the snowflake

You need 6 M5x18 bolts and nuts, or 6 #10 24-TPI ¾ bolts and nuts.
