Gasket and Sealant Scraper

In need of some plastic scrapers to remove old gaskets from a motorcycle motor without damaging the mating surfaces, I didn't have any good options around.  But, that's an easy problem to solve.  

I quickly drafted up four versions of a scraper with blade widths of ¼" (250 scraper), ½" (500 scraper), ¾" (750 scraper), and 1" (1000 scraper).  

I chose to print with 4 perimeters and 20% honeycomb infill.  PETG and PLA both seem to work well.  

To use the scraper, orient it with the flat side up and the angled edge of the blade against the flat surface.  This seems to work best.  Optionally, you can sand the angled side of the blade to reduce the ridges from the printed layers.
