Halloween 3D Printed Pumpkins

I can't take credit for this one. I subscribe to the Newton Free Library events calendar because they have lots of great examples of STEM programming and this one particularly struck me. This October they are virtually "carving" pumpkins in Tinkercad. Thanks John Walsh!

The skills learned in Tinkercad for this project are holes, grouping, using multiple workplanes and rotating shapes. TIP: Make sure to leave plenty of room between the eyes and the mouth or it won't have enough solidity to print properly. I left 11mm distance between the end of the eyes and the beginning of the mouth. 

Step 1:
I imported a pumpkin shape from the web and added a sphere from the pre-made shapes on the left sidebar of Tinkercad.


Step 2: I added a new workplane on the front center of the sphere (now orange grid appears). I used the roof for eyes and the round roof for the mouth out of the pre-made shapes. The shapes needed to be sized and rotated. Then grouped it all together.


Step 4: I made all of it a hole which is the essential "carving" of the pumpkin and moved it into the center of the white pumpkin. This would make the inside hollow for the most part and cut down on printing time. Plus it will add dramatic effect when a light is shined through it.



Step 3: I grouped everything together.




It took about 4 hours to print a 50 x 50 x 61 mm (ish) pumpkin without any supports besides the brim. (Supports are a PAIN to get out of the pumpkin this small). CURA set up was for "normal print" with print speed of 50mm/s.













Anyone who knows me will not be surprised that my second one was a cat!
HAPPY HALLOWEEN!

  1. Thanks for sharing this. I have a 3D Printing Workshop for teens coming up in a couple of weeks and I think this would be a great component to it!

3D Printing Tips

Here are some go to tools to have when 3D printing: box cutter, needle nose pliers, wire snips

The wire snips are handy when you build any kind of supports or rafts onto your project and you need to carefully cut them off. The needle nose pliers I usually use to remove gunk from the tip of the extruder and the boxcutter was for getting off those 3D printed jobs that have stuck themselves to the non heated plate.

My newest tool: painter's tape. Sometimes the simplest things can make life easier. As I was struggling with my box cutter to pry a 3D creation from our Cube 2 non heated plate, a man went by our table at the Cape Cod Mini Maker Faire and said, "Oh just cover the plate with painter's tape". EUREKA! I still have to cover the masking tape with our special glue before printing but now when I try to pull off the creation I just pull at a tape strip and it comes off easily. No more soaking the plate for 10 minutes in hot water or prying it off with a knife (or in th…

Makey Makey Floor Piano

If you are looking for a short, low cost project to do with your Makey Makeys, this one is sure to be a big hit. It's a great small group project as well as an eye catching interactive display in some noisy area of the library (as long as you can keep library staff sane). This was made as part of our Tinkering Tuesdays lab. We had low tech cardboard construction, 3D printing, and the Makey floor piano going on simultaneously. It took us about 1.5 hours with 3 teens helping.

Materials List:
Aluminum Tape $12
Duct Tape (any color) $2
Makey Makey $50
CAT cable (there's one lying around your library trust me) or just use regular wire
Wire strippers
12 x 12 x 1.5 in puzzle piece exercise mat $12
white 6 x 8 tarp (but could be smaller) $12
Computer with internet running Scratch

This video shows a demonstration with step by step picture instructions and a more detailed video explanation. I got the idea from two sites that I used for consult: Ed Tech Junkies & Make It At Your Li…

Podcast on Pokemon Go

Here is our podcast on the subject starring myself, Beth (circulation/tech services) and Suzanne (reference/YA) As we keep playing, we start to learn the finer details behind the Pokemon Go phenomenon and explain it for non-users or the curious. On a side note: I am now level 19 :)
