A fairly inconspicuous pumpkin, until you pull back on the stem…

Assembly:

Glue the teeth to the halves, align using the front edge and the middle segment crease

Glue in the eyes and stem to the upper pumpkin half

The stem has a little notch on the underside if you want to slide a keychain into it before adhering it to the pumpkin

Slide the rod piece through the two hinge pieces

Slide the the longer side of the hinge assembly into the lower pumpkin half, in my testing this should be a secure fit, but a little drop of glue won't hurt.

Angle the other hinge half upwards and drop down over it the upper pumpkin half

Chomp away

Plates 1-3 are the single parts split by color

Plate 4 is everything printed by object on one plate, small enough for the A1 mini
