  1. To create the shield, 3D print the top and bottom parts. Download the files for free from websites like Thiniverse or Prusa, or access them from the zipped folder provided here.

  2. You can use a standard white elastic band, but one with buttonholes is preferable.

  3. First, wash the bottle. Then, cut off the top and bottom. Finally, cut the side to open the plastic.

  4. Instructions for Assembling the Bottle

    1. Prepare the Bottle Base
      Open the PET bottle and insert it into the slit at the bottom. Use a soldering iron to melt the PET and printed parts at three visible interior points.

    2. Attach the Top Part

      • Mark where to create holes in the bottle using a marker.
      • Melt the holes with a soldering iron.
      • After securing the top part, further melt the plastic together for enhanced durability.
  5. Use nail scissors to round the corners at the bottom of the PET shield. Normal scissors can be used as an alternative.

  6. Firstly, cut approximately 6-8 inches (16-20 cm) of elastic band. Securely tie the band around the holders on both sides.

  7. Disinfect the inner side of the shield to remove bacteria. PRUSA provides a Sterilization Guide for further details.
