The current global pandemic has spurred many people to search for ways to help support the overstretched medical system and many designs for personal protective equipment can now be found online, with examples ranging from 3D printed masks, to replacement respirator parts and Venturi valves, to DIY face shields.
In this guide, we’ll show how you can make this design with a 3D printer and a 2 Liter PET bottle or two (3 L may work even better if you can get one!) in case you do not have a laser cutter or Cricut vinyl/craft cutter.
Have an amazing project to share? The Electronics Show and Tell is every Wednesday at 7:30pm ET! To join, head over to YouTube and check out the show’s live chat and our Discord!
