Yeah, that was my first thought. By now 3D printing technology has improved so much, that surely no-one would dare to let anything going to customers look like that.
I really can't tell if that's better. Going by the one image there (unsure if there's some thread on X that is being hidden from me), the buttons look 3D printed, there's some very weird serial number(?) or something that looks poorly 3D printed on the bottom, and we can't see the edges, so no idea if the layers are visible or not.
Yeah the lettering is terrible and oh god those buttons. Couldn't he just have bought some injection moulded ones and designed around those?
I had that 555 timer book and project kit as a kid.
Unless the goal is just to fulfil an obligation and get the hell out.
