Well, i'm doing my engineering studies, and I often get annoyed with friends, when needing a flat or phillips screwdriver, and I obviously don't have one under the hand, so I made that one that fits discretly in my pencil case !

Avoid using supports for printing, they might just annoy you !

You can pause print at layer height and add a round magnet that's 6x6x4mm

I'm not responsible of anything if you damage your printer when adding the magnet during the printing process, but keep in made to do it safely !
