Skateboard Tail Sparker(HOTRIDER)

This is my own take on the popular product Tail Devil for skateboards. Requires minor drilling into the board but as long as you use flat bolts it doesn't affect the feel or riding at all. I used M3 bolts and nuts but you can use whatever size you want as long as it's sturdy enough. The way I mounted it to my board was by the tail and drilled 3 holes in a triangular shape for 3 bolts. If your bolts aren't flat you can grind the tops down a little but it's easier to just get flat Philips head bolts.

THE SPARKS:
I designed this to work with 8mm flint and magnesium rods I got off Amazon(NOT AFFILIATED, JUST THE PRODUCT I HAPPENED TO PICK) and it's lasted me for multiple months

I usually cut them to a size a couple of millimeters more than the height of the hole, but there's no magic size. Be aware that the longer you chose to make the rods, the higher chance they have of snapping in use. You can use a hammer or a vice or really any method to put the rods in the holes, and it holds pretty well with just a friction fit, although you could add a little bit of superglue to hold them in better. To remove the rods, I like to drill a small hole at the bottom of the rod holes and when the rods are spent, I just hit them out with a nail. They last anywhere from a couple hours to days depending on how frequently I'm making sparks.

PRINTING SETTINGS:
Infill: 100%
YOU MUST PRINT THE PART AT 100% INFILL!!!!
This is very important for the functionality as low infills tend to get ripped apart by the huge force the part experiences
Be aware that even at 100% infill the part will experience stress and probably get ripped apart at one point or another, it's just the limitations of the material.
Material: PLA
Supports: None

I like to drill a pilot hole and then put some bolts in near the top of the Hotrider for extra protection against wear and tear from asphalt(reference picture of the part mounted on the tail), but again the plastic will get worn down eventually.

I have also attached the Fusion360 file, so feel free to modify it to fit your own requirements!
