Picture of Adventure Time Earrings or Necklace
My best friend loves Adventure Time, and admittedly, I love it too. She also loves earrings, and makes jewelry like crazy, but often for other people and never herself. I decided to combine her loves and make her some Finn earrings.

I made it at TechShopSF!

Step 1: Materials

Picture of Materials
For this project I used:

Epilog Laser Cutter
24"x24"x1/8" plywood
4mm and 6mm Silver Jump Rings
Earring Posts and Back
18" chain
Claw clasp
2 small tipped pliers

I had to go to a specialty store to find the 1/8" plywood, so call around before you run off to Home Depot or Lowes.

Step 2: Masking your wood.

I have learned from cutting wood with lasers, that smoke can burn your wood, and be difficult to sand out. Applying masking tape to both sides of your material does not solve this problem, but it helps a bit.  I used 24" wide masking tape on a roller to skin my plywood, but if you can't find that at your hardware store, just get some 3" tape and make multiple passes.

Cover both sides, smoke can damage both the top and bottom layer of the plywood.

Step 3: Draft a file.

I did an image search for "Finn Adventure Time" and found a Finn I thought I would be able to replicate in a digital drafting program. I used CorelDraw to generate the file.

All of your lines that you want the laser to cut must be set to hairline thickness in Corel, any thicker lines will be etched. All of the lines I wanted etched, I set to .5 pt thickness. I extended, or bled, my etch lines beyond the cut lines so that they would look cleaner.

Each of the holes is .1 inch diameter, which is just big enough to get jump rings through.

I used the Pen tool to draft the form, the shape tool to tweak the form, and then the circle tool to make the holes. It took me about 15 minutes to trace the original Finn, and make my own. (but I also attached the file)

Here are the Jakes I made too. They are all available here.

Having just received these myself, I can attest that these Finn and Jakes are just as mathematical in real life as they are in this instructable!

You should try a Jake the dog bracelet like this with a lot of body segments. You could have the clasp look like he's grabbing his own tail.

I am at TechShop now, cutting out Jakes. I am going to do Lady Rainicorns too I think. Oh, and B-Mos.
That's awesome. Adventure time is one of my most favourite shows.

Hi there,
I am new-ish to adventure time. I have seen it in passing but never really sat down and watched it...WOW! I love it! My son is 12 and he and i watch it together a lot...it's so fun to sit and trip on the creative minds of like minders!
Next on the awesome list...the regular show is a blast too! Dude, do me a solid....my son and i crack up!
I want to know how one finds people/places with a um...laser wood cutting machine. Is there laser cutting sites or stores? You sound like you have an awsome job by the way! Keri
