Real World aside: The other day I tried to 3D print small text. (Not super small, just the usual 0.4 nozzle size.) Comic Sans worked out best for this due to pretty constant line width.
(and if you're up for a rabbit hole, https://aresluna.org/the-hardest-working-font-in-manhattan/ )
Also, thank you for the "routed" tip. Your rabbit hole also mentions "monoline" and the MIL-SPEC-33558 font too.
I'd upvote you ten times if I could. Made my day.
I think this was what font they used except they had it all connected , that is if I am typing "test" then t is connected to e and then s and then t , in probably the same font as that of Comfortaa.
