Summary I wanted a tool holder that wasn't attacked to the printer. i made this one to fit all sorts of sizes of scrapers a swell not just the oem one that comes with monoprice and wanaho 3d printers. This stand holder the tweasers, the sd card, the hex keys that come with it, and almost any scraper. if the fit is too snug for your hex keys i suggest heating them up and pressing them in and wiggling them a bit so when it cools it will be a perfect fit.
