# 3D-printed Jack o' Lantern

Halloween is coming up soon and so I'm celebrating by making my own personal 3D-printed jack o' lantern. With an LED tea light inside it can glow without having to be too big.

This Instructable is a part of the 3D Creation Systems Jack o' Lantern challenge. You can enter by posting your own design to the contest. It can follow these instructions or be made entirely differently in the CAD program of your choice. Just make something spooky!

OK, let's make a 3D jack o' lantern

## Step 1: Make a ball

There it is. A sphere!

## Step 2: Squeeze it

Non-uniform scale of .8 in y axis

## Step 3: Copy it

Make a copy of the ball and move it over

## Step 4: Copy the copies

Copy that pair and rotate the new pair 36 degrees

## Step 5: Repeat!

Make 3 more pairs of copies and you'll have the body of the pumpkin

## Step 6: Make a curved path

Draw a curved line

## Step 7: Draw a circle

Draw a circle at the endpoint of the path

## Step 8: Extend the circle

Rotate the circle to be perpendicular to the path and create the stem by following the path with the circle

## Step 9: Insert stem

Move the stem into place on the body of the pumpkin. You will likely need to change the scale of it

## Step 10: Combine

Connect all of the shapes together

## Step 11: Shell the pumpkin

Hollow out the pumpkin with the shell tool

## Step 12: Cut a hole in the bottom

Create a cylinder and subtract that from the main shape. You now have a hollow pumpkin with a space for a LED candle to be inserted.

## Step 13: Cut a face

Make your own face for the jack o' lantern by subtracting different shapes. When you're happy with the results you can export an STL and print it!

I dot have a 3d printer :( could anyone print and send me one for a small fee?

I'm new to 123D Design. how would you go about subtracting shapes from the pumpkin's "face"? Any help would would be appreciated, Thank You!

Good question. In the desktop app it's like this
1. Select the "combine" tool
2. Select the item you want to keep
3. Select the item you want to cut it with
4. Select the "subtract" option from the icon at the end
5. Hit Enter

Here's what that looks like

Question for those of us without idevices (sad face) what are the units for which you use "3" as the measurement, and what is the diameter of the cylinder? (preferably in mm)
fungus amungus (author)  Shantorian3d1 year ago
it's mm. No need for an apple product, though. 123D Design is free on PC as well. There's also the web-based version.

I'm running Fedora 19 on my PC, and it doesn't seem to like chrome. Also, there's no down loadable version for Linux.
-no web gl in chrome
-no sound from chrome
-crashes when I run chrome
If you know how I can still use 123ddesign, though, it would be much appreciated.
-gums up the machine when chrome is working.

Maybe another browser then? Not sure, I don't have a Linux machine to test with.

Print out some food

OK, but it will be really crunchy

suggestions:
-eggs (minus the non-shell part)
-Doritos (plastic to begin with)
-diet taco shells (you wouldn't actually eat them, so zero calories)
try one!

I love it. And I have a suggestion: if you gave it three little legs, say 8mm high, the tea-light 'flame' would sit much more centrally in the pumpkin.
Alternatively you might devise a collar that holds it in a similar position.

This is awesome i actually want to go in the contest but when I saw yours I just can't be in the same contest
fungus amungus (author)  mtarek21 year ago
Well I can't win and you can enter just by modifying the file. Do it!

What kind of printer did you use? I ask because typical (inexpensive) extrusion type won't print a design like this without some support.
fungus amungus (author)  ledartist1 year ago
This was printed with a SLS printer. So it had the support of the non-sintered powder around it.
