Here's a quick print that's likely faster than carving a pumpkin and that's scaled to fit 200x200mm print beds. I wanted to create Halloween themed decor that would keep the pumpkin from potentially rotting before November. This was my first attempt with push-in pumpkin decorations. I had to increase the spike height and diameter a few times. After experimenting, I almost feel like short and stout spikes would be ideal as opposed to long and narrow. Either way, these spikes will allow re-use a handful of times before wearing down. Lifetime of the spikes will vary according to material and print settings. I went with standard PLA and the model flexes around the face of pumpkins with ease.
