Summary

Utilizing very similar design concepts to the Solar Sayings,
I optimized this version specifically for displaying acronyms.
Each portion of the acronym is displayed on a different line
with the first letter of each line displayed all the time.
As the sun moves through the sky, the different lines of the
acronym will display in sequence. I also provided a mechanism
to add a background image that constantly displays as well.
I decided to use the FIRST acronym as my prototype:
For
Inspiration and
Recognition in
Science and
Technology

Printing

I did have to make some changes to get the best results when printing this design
on my printer:

• Nozzle Diameter: 0.4mm
• Layer Height: 0.2mm
• Wall Generator: Arachne
• Elephant Foot Compensation: Disabled (especially for GnomonSlot)
• Bottom Surface Pattern: Aligned rectilinear (especially for GnomonSlot)
• Infill: Gyroid/Honeycomb (something that doesn't cross especially for GnomonSlot)
• Number of Top/Bottom Layers: Enough to cover DisplayThickness (especially for GnomonMask)

Be careful when removing the GnomonSlot from the build plate as many of these
elements are a bit fragile.

The GnomonMask and GnomonSlot parts are to be printed while sitting on their
outward facing sides.

Since it will be in the sun and as such needs to be printed
in a material that is stable when placed in the sun (PLA is not such a
material). I've been using PETG but there are likely some other high-temp,
non-flexible material will likely work.

Assembly

The two Gnomon halves fit together fairly easily and since there is no complicated
stand to assemble, I'll assume I don't need to generate an assembly video.
