Shut Off Signs (print on any Printer)

I created these signs in tinkercad to help my family and/or plumbing workers find the plumbing shutoff valves in the basement should I not be at home. I would hate for there to be a catastrophic leak and confusion to delay shutting the water off. 

I printed all of these with my Voron V0.2, in PLA to ensure they could be printed by anyone with a 3D Printer. The top of the letters were simply covered with a black sharpie. The sign measures 90x60mm.
