Step 1 : Materials & Tools

Here are materials that we used for this project. everything you see is standard
MATERIALS

Most of the materials are from the helmet itself.
We use straps and foam from the helmet.
Specifications: Size: XS 46-52 cm Weight: 230 grams
You will need a transparent plastic sheet, we used pvc, to make the shield
Velcro (but not that much, you can take some off the helmet you bought)
You will need screws and bolts, 16mm x 4mm (x2)
Rubber spacers for between helmet and the shield to create space in between (but you can use other alteratives.) We liked rubber because it provides flexibility. 16mm x 5 mm (x4)
TOOLS
Screwdriver: to mount the bolts
Dremel or drill with a 4mm drill bit. Bore 2 holes in helmet headband.
Use superglue, hot glue, or fabric glue to attach the velcro.
You're ready to go!

Step 2: Preparation Before Assembly

Remove everything inside the helmet; we need the headband tightening system, straps, velcro, and cushions.

Step 3: Parts From the Helmet

Now that we have everthing that we need form helmet, we need to add velcro to-

The straps
The sides of the headband tightening system

Step 4: Now We Bore Holes in the Frame and PVC Sheet

Cut your face shield out of the PVC.
Bore two holes in the pvc and headband, in order to attach the two.
Add screws and spacers to ensure alignment BEFORE drilling through PVC.

Step 5: Assembly

Now We have everything we need to make the helmet

Screw everything together
Be sure the bolt is threaded through your spacer, this will expose the threads allowing you to add the nut.
You can paint the visor as desired for sytle!
