The great Grace Hopper gave away lengths of wire to illustrate the distance light could travel in a single nanosecond. I needed to illustrate something similar in a presentation but showing a wire on stage isn't very visible. So, I made this model.

Printing tips:

I used a slicer pause to switch filaments and make the text visible. I printed it both text down and text up: I think the text down looks slightly better, although both seem to work. Top print in the photo is text up, bottom is text down.

Also, please don't scale this model ;)
