Halloween pumpkin with sliding ghosts

A cute halloween pumpkin with a mechanism inside that allows ghosts to come out from the sides of the pumpkin. 

The joint parts are drawn with a tolerance of 0.15 mm, but I also uploaded the .STEP files so you can edit them to match the tolerances of your printer (mainly for the sliding mechanism).
The joint for the stem is round so you can orient it as you like, then fix it with a bit of glue.
