"CALICO" DMFG, LLC is an independent design STUDIO located in the heart of Los Angeles, California.

We've chipped in our CNC milling resources to help out medical professionals and essential workers stay safe.
Here's how you can help, too.

For Manufacturers:

  • CAD files are available for these products so you can help your local community
  • Sourcing and material pricing listed for maximum efficiency
  • Reach out to hospitals and medical professionals for their procurement managers, but also remember firefighters, first responders, and all other essential worker categories.

For Essential Workers:

  • For local production, ask around for somebody with a "CNC Router"
  • Local schools, hobbyist groups may be available.
  • Lists like 100k Garages might help you find somebody, but ask any engineers or designers you may know.
  • Email us and we'll help you find somebody local if all else fails.

Polycarbonate Face Shield

Version 1.4 Updated 5/6/2020

Designed by Inside Weather, we have modifed it for easier strap usage and more cost efficient and easily removable double sided tape.

The mask can be disinfected, and new consumable foam pads and elastic straps can be installed for a very secure fit.

Parts List

Material Cost

  • Reusable shield is roughly $1.50
  • Consumable elastic and band are roughly $1.50

  • Nested with a 4x8 foot panel. If you don't have a vacuum hold down table, use double sided tape with at least a 12 cubic inches of tape contact per mask. That means apply to spoilboard about 6" apart, use roller to adhere tape, and then use shims to slide plastic on table if you don't have help maneuvering

  • Nesting assumes a 0.125" cutter, try to use a short 1-flute cutter like this one from Amana Tool and chuck it up as far in as you can before hitting the flutes to reduce chatter from excessive stickout.

  • One other thing you can do--mill the interior holes first, then screw a thin piece of plywood over the sheets with the screws going through the holes you just drilled. We're testing this technique but it might be possible to stack many sheets at once and mill them in one go with this strategy

Acrylic Intubator Shield

Version 1 Updated 4/15/2020

Initially designed by Dr. Hsien Yung Lai, we have modifed it for extra sturdiness by removing acrylic glue seams and replacing them with heat bends, as well as tapering the assembly slightly so units may stack and nest for better transport and storage.

This unit can be sterlized with 70% alcohol or bleach. We recommend using a good microfiber cloth to avoid microscratches that will fog the plastic over time. Do not clean with acetone.

You will need a strip heater like this or this. You can also just buy the element and build a metal enclosure around it.

Parts List

  • Main Wrap (0.125" thick, about 56" x 15.5", with two 92.5 degree bends 19" from either side)
  • Hand Panel (0.125" thick, about 19.9" x 19.1" adhered to end of bent piece

Material Cost

  • The shape affects how well they nest, so due to quantity your cost will vary.
  • One 4x8 sheet will nest 3 units with a few square feet of waste, so rougly $40-50 each
  • Three 4x10 sheets (2 sheets for wraps, 1 for hand panels) will nest 12 units with very little waste, so roughly $30 each

  • Nested with a 4x10 foot panel. If you don't have a vacuum hold down table, use double sided tape with at least a 12 cubic inches of tape contact per mask. That means apply to spoilboard about 6" apart, use roller to adhere tape, and then use shims to slide plastic on table if you don't have help maneuvering.

  • If you only have a 4x8" bed size, you should still get the 4x10 panels, break the toolpaths into two "halves" and just mill one side at a time with the other hanging over (or cut the panel into two 4x5 sections).

  • Nesting assumes a 0.25" cutter, try to use a short 1-flute cutter like this one from Amana Tool and chuck it up as far in as you can before hitting the flutes to reduce chatter from excessive stickout.

  • Also included in the file are two 0.5" plywood templates that you can lay the warmed plastic in for accurate bends and gluing. Mill a few of these for batching. 1st one sets up one bend, 2nd one sets up second bend and glueup.
