Lunar Lander (LEM) 0.728 high /w tube to suspend by wire

thingiverse

This is a 0.728 inch high model of the Apollo Lunar Excursion Module (LEM) used in two classes I teach. It is designed to be suspended by a wire (music wire or an unbent small paper clip) through the tube at the top and then formed into a lever arm to a hobby servo. The servo is driven by an analog circuit in one class to simulate a lunar landing (and the game Lunar Lander) and by a digital circuit in another to teach use of a microcontroller timer/counter. The second model is for a bracket to hold a micro-servo with a single attach pivot so it can be rotated to the correct orientation to index to the surface with the minimum pulse width. This prints best with a resin printer (it printed perfectly with vero white on Harvard's Stratasys Objet printer) but I have had success printing it on an Ultimaker 3. I have not had a high yield on a Prusa - the through hole usually does not print correctly. Ignore standards - Thingverse added them. I have no idea what them mean.
