ECOvid Protective Face Sheild

Fabrication

Material

• A4 transparent sheet
• Standard EU punch hole, 2 holes (exemple)
• 3d printed

Steps

• 3D print the face shield

Edit the model

The source (.blend) is included. It is composed of three separate parts, External, Internal and Strap. I rely on non-destructive modelling techniques and used a lot of boolean operations.

To adjust the height of the stack, select each part and edit the value count of the Array modifier.

To export the model, select the 3 parts and click Export on the 3D-print panel.

The following add-ons were used: Measure-it, 3D-Print Toolbox, Bool Tool, Curve Tools and Bezier Utilities. Freestyle for rendering.
