DIGITAL ITEM (printable PDF file): This is a basic hard hat printable templates and instruction for EVA foam, very simple and easy to modify. Ideal if you are a foam-smith, fan, collector or planing to cosplay.

WHAT IS INCLUDED
9-page print-only PDF file (digital template) set to print on US letter/or A4 paper size. All patterns are at a 1:1 scale, clearly marked and labelled with symbols and markers to give you a straightforward and pleasant crafting experience. Step-by-step drawings will help you with the most effective assembly order. Don’t forget to familiarise yourself with symbols, an edge-cutting chart, and recommended foam thicknesses on the explanatory page.

SIZE & FIT
All my DIY helmet patterns are designed to fit an average adult person, with a head circumference of approximately 57-59cm or 21-22in at 100% printing scale. But don’t worry—the PDF file includes a super handy and easy-to-read scaling chart. This chart allows you to adjust the size of the pattern to fit a smaller or larger head size by simply increasing or decreasing the printing scale.

EVA FOAM THICKNESS & QUANTITIES
To successfully build this project you will need:
8mm EVA foam - approx 45x55cm
6mm EVA foam - approx 20x30cm
Please keep in mind that the quantities above are the very minimum to craft just 1x helmet at standard size (100% printing scale). I highly recommend getting more foam - just to have extra material in case of any cutting mistakes or adjustments when crafting.

YOUTUBE STEP-BY-STEP VIDEO
Unfortunately, I don’t have at the moment a tutorial for this specific pattern. The good news is that the assembly process is very similar across all the projects - so make sure to check my YouTube channel and watch videos on other, similar projects, learn how to adjust the printing scale for your head size, how to apply contact cement glue and many more that will help you with your build.

SKILLS LEVEL
Intermedia - some previous EVA foam crafting experience is highly recommended. This project might require cutting some parts' edges at a specific angle and the assembly is a bit more complex, so make sure to check twice before you cut and refer to the assembly instructions. If you have questions - please message me, always happy to help and advise!
