Face Shield

This is a step by step explanation to show my face shield design. This will require a few store bought Items as wall as a 3D printer.

Supplies

1) 40in x .5in Velcro

2) Foam Window strips

3) 3D printer (STL. Code below)

4) Lamination Plastic sheets two 8.5 x 11in sheets

5) Two part epoxy

Step 1: 3D Printing

Below is an STL. File you can run though a slicer to print. It is recommended that your printing bed be 8in x 8in although a slightly smaller bed will do just fine. The size of this part is 6” x 2” x 2”. I used the app Shapr3D on my iPad. Small warning: the file is low resolution, this will cause a small triangle affect on the part.

Step 2: Prepping

For this step we will make the foam padding.

Cut two 6.5in x 1.75in long piece of foam trim.

Step 3: Velcro

Cut two pieces of Velcro

A) 12in x 1.75in

B) 28in x 1.75in

Next with these straps punch 6 hole in the middle spaced evenly by 1in each as seen in picture. You can use a drill, whole punch, or any other whole making device that produces a .25in whole. (Note does not have to be that size. It is only recommended do to peg size on 3D printed part.

Step 4: Shield

Outlined in Black is a two part face shield. This plastic is just a simple page of lamination plastic. You can pick this up at Office max for free is you smile and only ask for two sheets. Otherwise it is $30 for the whole pack of 20.

Sheet 1:

No cutting. Just punch six hole in the top about an inch down front the border length wise that match with the Velcro and head band.

Sheet 2:

Cut this sheet to the size of 11in x 3.5in and tape it with clear tape to the bottom of the first sheet.

Step 5: Assembly

In this video I demonstrated how to assemble your parts. First apply epoxy to the center cut out to glue strap A in place. Second Clip on face shield to the pegs. Next the pads onto the back. If they do not have an adhesive back like mine go ahead and use more glue and let it rest. Lastly, seat the Velcro onto the pegs. Optionally you can drill two holes and put screws in the far ends to help hold onto the parts.

Step 6: Conclusion

This in total costs $15 dollars. All of these can parts (not the 3D printed one) can be picked up at Home Depot. Thank you for exploring my project! Best of Luck.
