Do Not Dumb Here Workplace Safety Signage

thingiverse

The bold text and expressive iconography ensure universal acknowledgement of the requirement that dumb activities, conversations, and ideas are prohibited. --- My production print was done in white PLA+ at a low infill, then finished off with felt-tipped indelible ink markers (also known as a Sharpie). Where bleeding or accidental marks were evident, I used a fine-tipped paintbrush dipped in isopropyl alcohol to dissolve the ink, and then dabbed with a cotton swab to remove the residue.
