Welding respirator holder

thingiverse

This a clip designed to be used with a Miller LPR-100 half-mask respirator along with a 3M 9100XX Speedglas welding mask. Remove the plastic elastic harness and replace with this. It aligns with the vents in the welding hood to hold the mask in place while welding. Drops out into your hand when you lift the mask. Instructions Used Slic3r. Turned on support material ignoring everything more than 30 degrees. Printed with ring down. Cut off pedestal from center piece (auto-generated support proved insufficient for the center piece which doesn't tie in until the end of the print). I found just crushing the pedestal with a pair of long nose pliers works better than trying to reach in with an X-acto. Once it is pulled off, I cleaned up with the knife and hit it with hot air to heal the scratches.
