I couldnt find any 360 degree wheels locally wich I could have a hole in the middle for the crankshaft. So I made my own. Print out the PDF file (or high-res jpg) on your printer and glue it on a piece of plastic card with a spray glue or simmilar. Use an sharp knife and cut an circle just inside the dotted circle outline. Use an body-reamer to open up the crankshaft hole... Simple, right?
