This is model of the Captain America shield as a museum exposure, as you could see in "The Falcon and The winter Soldier" series. The base is 120 mm long and 70 mm wide. The shield is 100 mm in diameter. You can print it on FDM or resin printer, there are files for print it in one piece or in 4 pices. Personaly, I Printed the shield on resin printer in one piece, because it has cleaner finish and base and shield support were printed on FDM printer. From the added pictures you can see how to put it all together.
I am planning to do more of these MCU museum exposures and if you have any ideas what else i should make, please write me. Also, I made Thor's hammer - museum exposure, you can see it here https://www.nikkoindustries.com/products/thors-hammer-museum-exposure
