This is my first experience with Pepakura, and I wanted to build a Rocketeer Helmet.
I have the pepakura file on my website: monksvoice.com/Rocketeer
So, I downloaded Pepakura and ran it on Virtual Box on my Mac. The helmet file is easy enough to find. I didn't do any modifications to the file itself, I just printed it out on some matte paper and started cutting pieces out.
Here's a list of materials:
matte paper or any heavy stock
razor knife and scissors
fiberglass and resin
Gold Rub and Buff
1/8" tinted acrylic
Lots of pieces! This was actually kid of fun. I carefully cut out each piece and attempted to keep the numbers together, so I wouldn't have to go searching for them later.
That was wishful thinking. Searching for the attaching number and tab was a puzzle! I used superglue to bond the paper together.
