Size Matters

I went to pick up some 3D printed partsa yesterday.  When uploading an STL file to the website, you need to click mm, cm, or in for scale. Leave at the default of cm and you get this.

The babies on the left compared to the right size on the right.  Not the printer's fault.  Just be careful about units of measurement.

Very important for Mars landers as well.

Something like that shouldn't have a default. For obvious reasons.

This reminds me of that scene in "This is Spinal Tap" where the Stonehenge prop that Nigel designs on a napkin ends up being built 18 inches high rather than 18 feet because he got the symbol for the units wrong.

"I do not, for one, think that the problem was that the band was down. I think that the problem *may* have been, that there was a Stonehenge monument on the stage that was in danger of being *crushed* by a *dwarf*. Alright? That tended to understate the hugeness of the object."

That's just a little mistake, not a Gimli Glider mistake.
