The file 'Tactical Switchblade Letter Opener And Desk Toy 3D Printer Model' is (stl) file type, size is 222.7KB.
Heavily remixed from mathiaspl20
Designed this as a fidget toy that functions as a letter opener, yet looks tactical enough to be cool. You'd need a single rubber band and a well tuned 3D printer with tight tolerances.
It works amazingly well for me.
Disclaimer: Use responsibly and with caution. The blade edges and tip can be rather sharp, though they've been designed to have a thickness and the tip has been rounded.
