15% Gyroid infill; supports needed. I used tree supports, but I put .3 for the upper and lower interface of the supports.

There is a separate 3MF file for the for the HueForge ocean floor due to the much thinner layers than the main whale model.

Instructions for the sea surface:

If you use the 3MF file, the filament changes will be set. To print the sea surface, I used four colors: Inland White PLA+, Sunlu meta Green, Creality Blue Hyper PLA, and Inland Black PLA+. You'll want the first layer to be 0.16 mm thick, and all other layers to be .08 thick. Start the print with black. At layer 8, change to Meta Green. At layer 13 switch to Hyper Blue. At layer 19 switch to white and complete the sea surface print.

To assemble, start with the black platform and glue the sea surface to the top, aligning the hole of the surface with the cone of the platform. Next add the foam over the cone. Notice that orientation is important for a good fit.

For the whale, assemble the dark and light flipers, left and right. The right flipper won't have a peg, where the left does. (There is a hole in the whale body for the right flipper, but the peg didn't fit properly, so I deleted it). Next, glue the white belly to the whale body, then attach the flippers. Finally, set the whale into the mount on the platform.

UPDATE: I just updated the foam cone. The original had some VERY small floating pieces that I hadn't noticed, and it made no difference in the print. However, someone upscaled it to 300% to print on an Elegoo Giga Orange, and at that size, it wants to put floating strings of filament in mid-air, or add supports where none are needed. I've eliminated the floating pieces and put it the STL up as "Foam V2." The original is still there in case it's needed. Enjoy!

Then enjoy!
