Misplace your earplugs after a nights sleep? Here's a box for earplugs with embedded magnets. If you have a lamp, bed, or bedside table with metal in it, you can easily attach this little box to never misplace your earplugs ever again. You need one or two magnets of max 6 mm wide and 2 mm high. I used 20mm long, but there is more room. Pause the print (in your slicer) when you reach the top of the holes. (Or use my printfiles.) Embed the magnets. Continue printing. 

Sleep well!
