This degenerated, but I do like the ability to estimate with body parts. 300 mm does nothing for me mentally. 30.0 cm does a better job.

The TS/OP can 3D print a part. Also look for ones that have already been done.

Good thing there was no problem with changing from " cps, kcps & Mcps "
to " Hz, kHz and MHz ".

I still write Mc on whiteboards and paper schematics, because it's
faster. The official switch to hertz predates me, but I always did like
old radio books--I'm just re-reading "Superregenerative Receivers" by
Whitehead. Magic.
