Fixed Totoro cookie cutter

This is a fix for just the inner detail stamping part of [LettucePrint's Totoro Cookie cutter](https://www.thingiverse.com/thing:3785866). It extends the details on the chest down to the buildplate so they can be printed without supports, and fills those chest details in solid so that they don't trap cookie dough.
