I hate how flimsy the pumpkin cutters you can buy are. So I whipped up a handle for some jigsaw blades i had lying around. It worked tremendously. I've only printed the version in two halves. I included the solid one in case somebody wanted it. The holes are sized for m3 screws and nuts. The nuts sink in with a little bit of torque and that helps hold them in place. But yeah, it's not rocket surgery, take two halves and sandwich your jigsaw blade in between. Add screws and nuts.

I hope this helps somebody to have some fun carving pumpkins
