Basic Craft Foam Attack on Titan 3DMG Blade Tutorial
Disclaimer: By no means is this most exact or realistic way to make 3DMG but it makes due for a fairly decent con-safe cosplay prop that doesn’t weigh a ton or cost a fortune. This tutorial is only for the blades, but you can use the same basic principles and materials to make most of the other parts as well.
-Heather
What you are going to need:
1 36” sheet of white foam board (from Michael’s)
1-2 (12” x 18”) sheets of white craft foam (I used Creatology Fun Foam)
Black acrylic paint
White acrylic paint
Brown acrylic paint
Silver 3D fabric paint (in the little squirt bottles for detailing)
Silver metallic paint (I used Dazzling Metallics by DecoArt)
Exacto-knife
Glue gun (make sure you have lots of glue sticks)
2 black pipecleaners
Fine tip black sharpie
Small paint brushes
Pencil
Tracing paper (or regular printer paper works as well)
1 small sheet of sand paper

Step 1: 
References


These are the references I used for my blades, handle details and coloring. The black and white reference I scaled on my computer screen to match the length of 6.5 inches and then carefully traced it onto paper, making sure to include all the major details.
Step 2:
Cut out the outline of the paper handle you’ve drawn and place it on your piece of foam board. Trace around the outline and in the finger slots (minus the small part covering the part that looks like a bike break handle, that part will be added later).
Step 3:
Next draw in the blade dimensions. I included the blade dimensions I used and the blade angles in the reference pictures above.

Step 4:
Using an exacto knife, carefully cut out the entire body of your blade in 1 piece.

Next, carefully sand the edges to remove any bumps left when cutting.

Step 5:
Use your paper pattern of the handle details and start cutting out the major raised details. Be sure to cut 2 of everything, there are 2 sides to the handle.
Take these pieces and trace them onto your sheet of craft foam.

Step 6:
Start hot-gluing the pieces in place on the foam board base. Be careful with the hot glue because it will slightly melt the craft foam. Once things are glued, they are there permanently. If you try to remove anything, the craft foam will rip or tear and you’ll have to start over so take your time doing this! If you have a cooler setting on your glue gun, I’d advise using that.


Step 7:
Trace out a piece like the one shown below to cover the bike handle part on the craft foam, cut it out and carefully glue it into place bending it over the handle part.


Step 8:
Using the puffy paint, add in your details such as bolts or raised ridges (the picture below shows where I had already started painting the blades once the puffy paint had dried).

Step 9:
Once everything is dry it’s time for painting. You can choose to seal your craft foam but I tend to skip that step and just paint a couple extra coats of acrylic paint. You are going to need about 2-4 coats of paint to make sure your colors come out even.
Step 10:
Blade detailing. I marked off a line along the longer side (shown as the top of the blade in the pic below) of the blade that was 1/2” thick with painters tape. I then mixed some silver metallic paint with white to get a slightly lighter silver and lightly painted that area to give it the look of a blade edge. Repeat on the other side.

Be careful when removing the painters tape. I do not suggest using anything stronger than masking tape for this part as it could damage the foam board.
Step 11:
There are 6 dark lines along the blade. I measured mine to be able 4” apart at 20 degree angles, following the edge of the blade. I drew these in with a fine-tipped sharpie. Repeat on the other side.
Step 12:
Detailing the grip. What I did for this is I took 1 pipecleaner and used it as a sort of stamp. I carefully dipped it in black paint and dabbed off the excess then stamped across the grip in diagonals to get the grippy effect.


Step 13:
Next you’re going to want to cut 1 of your pipecleaners into thirds. Take 1 third and carefully glue the one edge under the bike handle overlap and the other on the face of the handle to act as the wires that control the blade. Only do this on 1 side of the blade (the side where the bike handle is facing to the right).

Step 14:
Repeat all steps for your second blade.
Step 15:
Go save the world from Titans.
Step 16:
Try not to get eaten.
