Ok this little bastard took 30 mins to draw, this basic part is a pressure sensitive valve for a hydrogen storage unit to convert a home into a self reliant power source, there is a lot more detail to be added just it took 6 hours to actually install the program. There are a lot more parts for this project to and i have to create this entire system in less then 24 hours so i will post other stuff later but keep in mind this is all drawn and there is NO way around it. All nuts bolts threads you name it had to be drawn and it all has to function so it can be printed in a 3D modeling machine for a product demonstration... Wish me luck this is a final for school *Crosses my paws*
