I think this is a totally cool way to decorate your pumpkin, and it has some advantages over traditional carving:
1. Next year, you can reuse what you already designed/printed
2. You can take advantage of what others design and publish
3. You can have really great results even if you are not a super skilled hand artist!
Now that you are totally interested, keep reading and let me know how it goes ;)
Step 1: Designing
The only model I didn't design is the Velociraptor Claw, which I got from Thingiverse.
Step 2: Printing
Anyway, this was my printing setup:
• PLA, 180°
• No support, no raft
• 2 layers shell thickness
• 10% infill
Before printing, you should consider the dimensions of the pumpkin for which you are printing the models, and scale them accordingly. With this scale, they look awesome on a 40cm diameter pumpkin.
At the end of this step you'll be able to download all of the models.
If you have any doubts, just ask me in the comments.
Step 3: Preparing and Cutting the Pumpkin
Then you can just use a knife and cut the holes. Honestly, my first idea was to carve a little bit the surface and then add the elements from the outside. Instead, I decided to make full holes and push the parts from the inside. This removes the need for glue and I think makes the composition look better, like if everything just popped out from inside of the diabolic pumpkin.
Step 4: Decorate
The pumpkin I had was not particularly big, so the final look was absolutely cool. If you are using a bigger pumpkin, then you may want to add some decoration, otherwise it may look a bit "empty". And don't forget to scale up the models!
Step 5: Final Thoughts
If you design more features, let me know in the comments, so I can put a link to your designs on this page!
Hope you enjoy, let me know how it goes the printing :)
