Scientific studies have shown that coronavirus can live on smooth surfaces for up to 72 hours, and on cardboard for up to 24 hours.

With social distancing in place, more and more of us are relying on delivery services to provide our daily needs. In order to keep things organized, and keep track of when things are 'safe', I started out making staging piles in my garage, with post-it notes on the floor... but I wanted something that was a better visual indicator, and that was more resilient & reusable than sticky notes.

Print instructions

The safe/day markers are 4mm thick, with a modified Source Sans Pro font for simplified printing. The provided GCODEs have an open bottom to cut down on filament use, and a hilbert curve infill pattern on the top to add a little texture. They also print fine on a 0.6mm nozzle. They're clearly visible from standing height, and will hopefully provide just a little bit of help to get you through this pandemic safely.
