​Blast by your rivals with this rocket powered snowboard!  Designed to be epoxied or glued directly onto the board.  It uses 24mm motors without ejection charges.  Print at 75-100% infill for obvious reasons.  If you want to put this on a skateboard like Mikey from TMNT make sure you have bindings of some sort to ensure the board doesn't fly out from under your feet and don't attempt stunts.  I have included a final version that you can print out immediately along with a D size engine template and the base alone if you wish to use different types of engines.  I'll hope to have one ready for next weekend to use for demonstration.I'm not responsible for anything that earns the reader a darwin award.  Please exercise caution during use and only use this on slow slopes or flat sections devoid of people and large jumps until you are accustomed to the acceleration and thrust.  ALWAYS WEAR HELMETS AND OTHER PROTECTIVE GEAR.  It might not be as fun but when you slip and flip headfirst into a wall or some ice you will be forever grateful for your helmet. Respect the hill, your fellow boarders and yourself and you will be okay.This has been entered in the 3D printing contest on instructables.com so any votes are welcome. :D
