Two versions:
 

Helldiver Plate STL: 

STL is straight up, will need to do your own coloring to your liking and arrange so it fits on your plate and is supported.
 

helldiver_plate_split_bambu:

For use with Bambu printers with AMS:

The one that I used for cut it up with some dovetails. Ended up using them mostly as guides, then using a 2 part 5 minute epoxy to secure the dove tails, and then used a junk soldering iron to plastic weld the inside of the plastic for more support and to not mess up the surface finish.
