Thanks for the responses everyone, I appreciate the comments. I like the idea about the LED on the end, it would be very easy to incorporate. I considered it at first but it’s a little tricky to show off in a render- I might post an update including it.
My concerns for making multiple things integrated were practicality, especially since you’d have a case to store things in. The speed and accuracy of the device isn’t something that I’d really have control over- since I’m just a designer. But I’d presume that since it would likely need/use modern updated hardware that speed and accuracy wouldn’t be a negative factor.
