This is a holdable shield that patients can use when seeing a dental professional (Dentist or Orthodontist) to minimize exposure for medical professionals when doing work on the mouth. When braces are removed, dust particles are released, and this helps to block them from reaching the doctor.
Use supports, as the shield is printed upside down to improve the stability of the clear plastic sheet. Up to 2 can fit on a build plate at one time with supports. I used a 0.6mm nozzle with PETG but it should work with almost anything.
