How about a analog mechanical 3D printer? (electric, electricity, software)

[plwhit]

Wait a minute, isn't this how we used to build things? Mechanically by hand?

Instead of building a traditional 3D printer, de Bruin decided to harken back to a past when pantographs and mills ruled the shop floor by making a device which doesn't require software or electricity to work its magic.

His 3D printer is driven by a 7.5 pound weight.
