MakeIt Labs is currently concentrating on three types of face shields, all of which use PET sheets that are laser cut. All except the Origami design are cut using the template for the Delve faceshield. 

Frameless Faceshield (Delve, Origami)

Delve

Laser cut shield, Assembled with foam/elastic

Our current "recipe" comes from delve.com: https://www.delve.com/insights/face-shield-designs-to-fill-the-gap

Here's a one-page summary of the design: PAGE2 US LETTER.pdf

The template for the shape of the shield: https://www.delve.com/assets/documents/Open-Source-Face-Shield-Drawing.pdf

Origami (being tested/vetted as of 04/01/20 10:00PM, looking good so far)

• • All-PET faceshield, can be cut with lasert/die-cut/cnc/waterjet

• https://github.com/madmaxbr5/faceshield

  • Explanation and greater details here.

CNC Cut (Laser, Waterjet) Faceshield Frame (Wilson)

Wilson (designed at MakeIt Labs)

• • Based on the Budmen faceshield frame layout

  • Can be cut by lasercut, CNC or waterjet out of a flat piece of PETG plastic 1/8" thick.

  • Uses foam against the brim to provide a good comfortable seal against the forehead

  • The foam will need a slit cut about halfway through to afix to the frame.

  • It was design for use with a 9" length of 3/8" pipe insulation which has a precut slit.

  • Has Headband attachment prongs similar to the Prusa faceshield.

  • Uses 13" Delve size PET shield with Budmen V4 holes and slots

• Wilson V5  (SVG, DXF) [196.151mm x 115.533]

• When using DXF files please refer to sizes above to rescale in your cutting software (if necessary).

Mega Wilson Faceshield for Dentists (designed at MakeIt Labs)

• • • Based on the Budmen faceshield frame layout

    • Can be cut by lasercut, CNC or waterjet out of a flat piece of PETG plastic 1/8" thick.

    • Uses foam against the brim to provide a good comfortable seal against the forehead

    • The foam will need a slit cut about halfway through to afix to the frame.

    • It was design for use with a 9" length of 3/8" pipe insulation which has a precut slit.

    • Has Headband attachment prongs similar to the Prusa faceshield.

    • Compatible with 13" Delve size PET shield with Budmen V3 holes, but for additional coverage you will need a larger shield

    • Wilson Mega V5 (SVG, DXF) [ bounding box 200mm x 140mm ]

    • For your reference an STL file is linked on the 3d Printing WIKI page.

3D Printed Faceshield Frame

3D-Printed "Budmen" Faceshields

• • A different model using 3D-printed structures for the shields

  • Better design than the Prusa b/c it has a closed top.

  • Design has been tested and approved by several hospitals, see"MakeIt PPE Projects" sheet.  

  • Currently there are two 'approved' designs for the Budmen shields.  V3 and V4.  The files are linked at the bottom of this page.  

  • We have a slight preference for the V3, but currently we are printing the flat budmen, ( see below ).

    • V3 - Zip file including instructions and the .stl files is below, download here.

• Flat Budmen is the fastest frame to print. It is basically the first 3.6mm of a Budmen V3.

• Models are available here: ( ABS, PETG, PLA, other )

  • The Budmen frames can accept a 13" Delve size PET shield with Budmen holes laser cut ( or punched using the template on the Budmen website. )

3d-Printed "Wilson" Faceshield

• The Wilson was designed to be laser cut, but it works as a 3D print as well. 

  • Wilson V5 is compatible with the Budmen Faceshield  layout

  • The models are labeled so the user can tell what material it is printed from ( ABS, PETG. PLA, other )

• Lasercut PET Shields

PET donations

Makeit Labs has received a donation of multiple rolls of PET plastic in both 0.010" and 0.0135" thickness, and a variety of widths.

Materials from McMaster-Carr:

• • Elastic Headband: https://www.mcmaster.com/88225k68

  • Foam: https://www.mcmaster.com/8614k84

  • Clear Shield: https://www.mcmaster.com/8567k64

Makeit Labs is meeting with die cutters with available bandwidth to accelerate production, but is also making sheets available to area makerspaces, and working to coordinate more national level supply chain logistics.

Process to request PET

1) Contact covid19-response@makeitlabs.com with "PET REQUEST" in the subject line

2) Provide contact info:

- Who are you

- What group are you part of

- What hospital(s) or facilities are you working with

- How much can you use

Additional info: (from Bill, loosely interpreted) Updated 3/25/20 @ 2:35PM EST

• • PET Sourcing: Need national-level distribution points willing to receive, have national level suppliers meetings in progress today. Some progress there with OSCMS and HE

  • Regional PET: Sourcing is not an issue. We can get as much as needed locally. Can get commercial fab in touch with commercial accounts at national supplier easily and quickly. 

  • Distribution: Waiting on protocols from hospital(s) on how the want to receive. Hospitals will be more picky, but minimum should be a wash/soak line for any recipient on shields. TBD on foam.

  • Foam:

    • FujiFilm looking into it, open to other sources.

    • Custom Die-cut in Windham able to source neoprene foam that they can apply adhesive and backer to, cost still pending.

  • Elastic Straps: FujiFilm looking into it.

    • Diecutusa has sourced 50 yard rolls of 1 inch white elastic at $20/roll.
