I always have this problem of creating simple things, I start with something simple and then I can't stop myself from adding more and more details. This time I managed to hold myself back! This is Eggplant Jack, a very simple...well Eggplant Jack-O'-Lantern. There are 3 versions each version has a normal and "full" version - The Full version has a non-cut bottom in case you want to print it complete so it doesn't stand.
Full Jack = Not Hollow
Hollow Jack = Hollow
Hole Jack = Hollow + Has a hole behind him to put tealight or whatever.
Placing lights inside can be tricky unless you print him really big - Just take that into account.
Printing:
Printing the hollow version can be a bit tricky TBH - You HAVE to make sure you have very good supports for the upper teeth part - If it's not strong enough it will fall mid print!
You can also print Jack upside down which will require less tricky supports but supports scars will be more visible.
Up to you :)
