This is a button protector for the OMTech Polar 350.  On occasion when using my Polar, I've accidentally hit the button with my arm, thus interrupting operations.  This protector/cover is the perfect solution to prevent that from happening.  It fits perfectly over the button and can either be non-adhered or affixed in place using double-sided tape on the bottom.

DIRECTIONS

I printed in “clear” PETG to allow the ring light to illuminate it at 0.2 mm layer height, no supports/brim, and 100% infill.  Also, print the model upside down (default orientation in file).
