I have a family member who works in a hospital out in Victoria, BC, and they asked me if I could make some of these that say Victoria Strong. They don't look as good as the design they're remixed from, but they work!

.28

If you use a layer height of .28, it will print in 5 layers.

Personally, I like to use a .6mm nozzle, set the initial layer height to .28mm, then every other layer to .32mm. This lets them print in only 4 layers, saving some time. If you use .32 everywhere, the letters won't show up on the print.

To see the letters better, I like to set my slicer to change filament at layer 2 and switch to a contrasting colour. Otherwise, the text won't stand out as much.

Be careful about pulling these off the bed too early if you print in PLA. They're so thin that they'll bend, then cool that way if the bed is still hot.
