Update: After testing this print I recommend using a stronger material than normal PLA. As stated before, use a kitchen knife to make initial cuts. You can also scale up on the z axis to make the whole tool thicker. It is plenty sharp enough to make clean cuts though!
Simple saw to save you the time and trouble of going out to the store to get one. Use a kitchen knife to make initial cuts in the pumpkin to avoid stressing the blade. Play with the scaling to create larger or finer tooth tools! Example is printed at 130% size.
Print in current orientation and support the blade. I would recommend against printing upright as this may make the blade more prone to snapping off.
This saw is sharp. Please use caution if you intend to let a child use this. There is also a chance the blade could snap so let the tool do the work and don't force it.
