Laser cut ruler? Answered

I was thinking about a laser cut ruler. Is it really pointless? It will be made out of blue light-gathering acrylic. I was just wandering if it was going to be useless...

Kids used to make them & engrave name or sometimes cut templates into them - Good practice with precision.

In days of yore, producing accurate rulers was a task given to engineering or machining apprentices.

I see no reason why should not carry on the tradition - as well as working to ensure the final product was accurate, you could also include cut-outs to make stencils of useful shapes appropriate to your intended use (laboratory glassware, electrical symbols, scale out-lines of the main KNEX pieces?).

I will try to make a slideshow out of this. I'll stick to blue acrylic. I will add some electrical symbols and a name engravement.

. Define "useless." Or "useful."

useless as not a very good idea and useful as in can be a good thing in the case of maths or something like that.

.  Define "useless" from your point-of-view.
.  Or "useful" from your POV.
.  What I, or anyone else, thinks is useless/ful doesn't really matter.

I'm just saying that would it look kewl...

. Well, I don't know if that equates to useful (or not useless), but it sounds like reason enough to proceed. Take plenty of pics and publish an iBle.
