Razor Scraper Knife

thingiverse

I was inspired to create this because of the LOBOCNC scraper blade holder. It feels incredibly comfortable in my hand and I have found it extremely useful for opening boxes at work and for odd occasions when I need to scratch or scrape something. It works best if the retainer parts are printed out of PET-G or a similarly flexible material. The retainers need to flex over the detents in the guards to create the nice spring-loaded snapping action. Pay close attention to the retainers after printing, noting that there are four protrusions and two of them are farther to the outside than the other. Make sure they are oriented correctly with the detents in the guards. Also, the retainers do not look different in the pictures but the back one differs in that it has a hex cutout for the nut. I've included the SolidWorks data.
