Prints perfectly on .2 layer height with PLA. Holes are perfect for keychain threaded inserts from amazon. I left these in here as negative modifiers so they can be adjusted based on your specific tolerances. You can probably get away without any supports, but I use them just on the pumpkins mouth so that it comes out crisp.

1/8/2023: I added each keychain individually so you can grab what you want specifically. Per request, the unsupported pumpkin is also available, but you probably want supports on the mouth.
