USB Tesla Coil Toroid top load

thingiverse

You can get small Tesla Coil modules on eBay built around the Exciter Slayer circuit. However, they don't look right without a typical top load of the big coils. This print is a toroidal top load for the smallest modules I found. If you search eBay with these texts below, you'll find them. I spray painted it with zinc spray, usually used for corrosion protection in car repairs, to make it electrically conductive. It would be great to have feedback if someone printed this with conductive filament. It has a small recess at the bottom to allow easy placement on the coil. A drop of super glue holds it in place. I also added a boost converter module to boost 5V to 12V, so the coil runs fine from USB with 700mA @ 5V. It doesn't spray sparks at this power levels, but easily lights neon lamps.
