Since everyone seems to be all about space programs, here's a very silly joke device from 50 years back: The Zlotnian Calculator, "Official Digital Calculator of the Zlotnian Space Program"

While it was a joke, it was made by a very serious surveying instrument company, the Slope Indicator Company of Seattle, WA.

As yet, no 3D print file...
@vik when have I ever disappointed ...? Gimme a minute, just got to find the right font

@vik okay, now it's done:

The Zlotnian Calculator (reproduction) — https://www.printables.com/model/1672286-the-zlotnian-calculator-reproduction

I wouldn't normally print detailed stuff in PETG, but it was in the printer, so it's what I got.

I even fitted the optional memory function!

By 'eck, OpenSCAD's nightly's Manifold mode is quick. This was about 90 seconds to render, while regular OpenSCAD is 40 minutes (and 3.4 GB RAM) in with no end in sight

@scruss
A few days late for the 1st but still cool!
@vik the horrors are never ending, yet I remain silly
