good advice in Latin: "FESTINA LENTE" ("more haste, less speed")

I often make mistakes by trying to do things too quickly, whether it's in my 3d models, programming, packing—really everything.  getting into a rush is a bad idea.  so, I made this to remind myself to take a little more care when I am in a hurry.

the letters are tapered so that they'll fit in through the front and not fall through.  the holes are pretty generous, so the letters should slide easily—meaning you can pull them part way out and drop them in again while thinking about taking it easy with whatever you have to do

printing

because the letters are at an angle, they may be challenging to print.  in my 3mf, they have mouse ears turned on; for your printer that may not be enough, so take care with that.

otherwise, this should be easy to print.
