This is is 1:1 model of the M829a3 APFSDS round. It is only semi-accurate as some modifications have been made to make the model more print-friendly. It is a screw based system with quite tight tolerances. The model has an assembled height of ~950mm.
When printing on print beds with low adhesion parts may or may not break off before the print is finished.
There is 2 options for fins, the accurate ones (option 1) and the print-friendly ones (option 2). Printing the fins upside down works just fine too and is recommended for option 1.
The example print provided in the picture below was printed on a Elegoo Neptune 4 at 0.16mm and 250mm/s with regular PLA.
The sabot is not personally test-printed by me, print at own risk (risk being wasting material and time)
