I wanted to print the original model but had issues with supports, so I decided to remix it into a ‘plaque’ style, giving it a flat print surface but keeping the curve the the shield.
The pics show how there will be a slight overhang, in which supports will be needed/highly recommended.
The other pictures shows my basic layout on supporting the model best i could, it could be better I'm sure.
Printed on Ender 3 V3 SE in Black/Purple PLA, then painted with Paint Markers.
The author remixed this model.
Added a backing and supports to give a flat print surface
