First print of a MoI model on a Prusa i3 MK3 printer.

The MoI solid Tetrus model was chosen, and placed in the front view,
with the base on the x-axis. With MoI, the model was scaled down to better fit the printer platform. Further scaling can be done later in PruserSlicer 2.3. Either Metric or English dimensions can be used.
Exported the Tetrus in .stl format to a computer folder. Polygon number was left at mid-range. This ends MoI role, but the following tells how to get the model to the print stage.

Purchased USB based SD card reader, (Keep onn), and extra 32GB SDHC UHS-1 Card, (SanDisk). (Walmart) SD card was already formatted in FAT32.
(SD cards to use in the MK3 must be formatted in FAT32, so a 64GB card would have to be reformatted.) Prusa printer comes with an 8GB SD card, which holds only G-Code, for ~16 models. Copied 8GB SD card files to a Windows Folder, and also to the new SD card. Models should only be printed from an SD card, despite other possibilities.

PrusaSlicer is Prusa's embellishment of the open source program Slic3R, and seems very good, with added features. PrusaSlicer performs many tasks, with user inputs and interactions. Downloaded and installed PrusaSlicer 2.3, in Windows 10. Watched two UTube videos about PrusaSlicer, one by HardwareGuy, the other by Prusa (Painting support targets). Opened PrusaSlicer 2.3, and made lots of selections.
Tasks include Metric vs English dimensions, Loading the Tetrus.stl, Scaling, Printer settings, Filament selections, Infill selections, and Support selections. The Tetrus and settings can be saved in a 3MF file,
or (amf?), somewhere. Estimates of Filament usage length, and Print time is given. Print time depends upon the parameters chosen. Finally PrusaSlicer creates a GCode file. Copied the GCode file to the 32GB SD card. Either card could be used. Removed the SD card and inserted it in the MK3 printer. Ran the printer.
The GCode contains all of the CNC commands to tell the MK3 printer what to do. Several hours later...

Also came across information on PhotoGrammetry, which would not have much to do with MoI. Take a bunch of photo's of a "statue", and use free MeshRoom/ Alice Vision, to create a triangle mesh model.

The support in the Tetrus breaks away fairly easily. So did the Triceratops supports.
