Printable, is, as you might expect, a font designed to be easily printable. In this case, I designed this font to easily work with 3D printers. There are no floating components that would fall out, if you were to make cutouts of letters. Also, all lines are of uniform width to allow single line printing. Feel free to use this font for any personal projects. However, if you plan on using this for projects that may, even indirectly youtube videos, webpage ads, etc. earn money, please contact me first so we can come to an agreement. Thank you for understanding, and I hope this font serves you well. If anybody has any suggestions on how I might improve this font, please let me know.
