Inspired by this years Japan cup track, and the "Grumpy Changer" This is the first needed track model, a 45 degree bank with a printable support. From current views of the track the Grumpy Changer apears to be a 90 degree banked rainbow changer with something special in the middle. To begin work towards that I have worked on this. The model will need to be printed 4 times to get a 90 degree banking and a return. there is a modeled in support structure on one side of the track section to allow for easier printing and supporting of the track when setup. The provided support model is intended to support the bank section on the first level holding it at the 45 degree bank. It, the support model, is not meant to be print in place as the track should be print flat to reduce the ammount of support material needed.
