This is just the grumpy pumpkin cut via Netfabb so it has a flat bottom and doesn't require support or raft to print. Note, this was scaled to fit a giant 400x400x400mm printer. You might want to scale it to fit your platform.
I have not been able to make this as a "remix" of the Grump Pumpkin by user Scampbell.
I have no idea why thingiverse will not allow that, but a search never shows it??
