Slide Rule Core
by jwygralak67, published
This is a concept for a core that will join two halves of the Cylindrical Slide Rule by Mortimer.
I haven't had a chance to try printing this yet. The wall thickness and slot width will likely have to be adjusted in order to allow it to snap into place, yet hold together without falling out.
First, print the two parts of the Cylindrical Slide Rule
Then print this part (Joiner.stl)
Finally snap it all together.
Do NOT attempt to print assembled.stl
I only included that to illustrate the whole assembly.
