If you were happy with reels in contact, you could have one with no markings and one with 1cm calibrations which were actually 2cm apart. Reading this one where the tapes meet would give the total distance between the end tabs…but I’m sure there is a more elegant mechanical solution that also allows independent use of the reels.

Besides the orientation “back to back” the reels could be on a single axis, doubling the width of the device iso the length..
In the middle of that axis one could place a gearbox (differential?) to make the length visible?

A variation could be the measure-blok to measure two orthogonal distances to calculate an area.
And with 3 you could do the cube..

Could the “adding” could be done mechanically with a differential gear?

Thanks Rob,
I was hoping to create that yesterday but time was against me. Still thinking about it…
Cheers,

This is a very inspiring one!

How about a mechanical adder that could add up “the two reels” automatically?
(in digital world it is easier)
