Oh, man… sorry it’s coming off like that. Since it’s called the Humorless Toaster, the main inspiration is Ron Swanson. At least that’s what I was going for…
Agreed, wider and thicker with maybe a wavy/ ridge texture on the bottom half of the mustache and slight rounding/flaring on the sides that narrows to the top.
Have you tried a design where it has a mustache for a mouth? As another lemming described, wider and wavy at the bottom. And then it can move up and down when it talks?
