I built my own slide rule in school for fun! It looked pretty cool to me at the time. The template is still out there if you search something like "paper slide rule".
I've collected some links for building regular slide rules ([1] & [2]) as well as a circular slide rule [3]. Someone might also like the slide rule simulator [4].
