Two faces in one jack-o’-lantern!

New design for 2024! My 10-year-old son wanted to design something new for the elementary school pumpkin decorating contest. He won “Most Creative” with this design! We started with our base pumpkin model and then he drew the faces using the CAD software himself. His first hands-on experience! It was his idea to have an “Evil Face” and a “Happy Face.” We printed the large one for him to take to school. He set it up on a turntable and used a little black tissue paper which worked great to display the effect.

Jack-O’-Lanterns:

Exclusively on Cults!

The jack-o’-lantern base is approximately 120 x 120 x 95 mm. The lid and the stem are separate models since I originally designed them for two-color printing. The large print is 175% scale.

I printed with 0.25 mm layer height, 2 perimeters, 3 top and bottom layers, and 15% infill.

In the model there is a tiny gap in the design between the lid and the base. I have also printed jack-o’-lanterns at 75% scale.

This model needs supports.

Note About Supports:
We started with the large print. I used the organic/tree supports with the default settings in PrusaSlicer. In general they worked fine, but one tooth was not supported well and it broke off while printing. Since it was a large print, rather than reprinting it, we worked within the slicer to isolate the tooth and print just that part. My son used some 3D Gloop to stick it back on. See the last few photos.

Before printing the smaller ones, I added a support enforcer for the top teeth. This seemed to help. See the screenshot at end of the photos and the photos showing the supports after printing.
