The "Stanley Razor Scraper" (https://www.thingiverse.com/thing:2029655) is a very helpful little tool, but it is a matter of time to cut myself with it. That´s why I designed this cap. The model is for a 9x1.5mm magnet, but the Fusion 360 file can be edited to accommodate whatever is necessary.
 

The Fusion 360 files are also here.
