Razor Blade Scraper V3

This is a redesign of the last razor blade scraper i posted on here. V2.0 i presupported it on a 45deg angle so it could be printed for strength but there were some things i did not like which i corrected in this version. the blade now fits much better, slides in easier and also locks into place once its inserted so it will not slide out. the blade locks in to place with no tools necessary but can be removed easily when its time for a change. i also revamped the support where the 5 little tabs would need to be cut off and leave marks on the back side. the new support just barely touches the back leaving no marks. the support almost falls off when its done printing. i have been printing and using these scrapers almost daily for the past 13 years. these hold a std #9 single edge razor blade, available super cheap at almost any hardware store
