Spark plug snowflake maker!
Gotta love 3D printing! I came up with this design while working on a car themed Christmas wreath. If you're interested in more of the background info you can read more about project Merry Car-Mas Here!
Onto the details: It takes six NGK ZFR6F-11 spark plugs. May fit other spark plugs, but has not been tested. The holes in this snowflake adapter are designed to fit tight in order not to require any adhesive, you will need to thread the spark plugs in.
Print at 100% infill with supports.
I printed in ABS, PLA should also work fine.
