MZ4250's fire giant, split up with registration pegs for easier printing. Head has a version with custom supports. It's also scaled up somewhere around 10% to more closely match the size of WotC's Fire Giant from Storm King's Thunder. (Base is scaled down appropriately to keep it the correct diameter for a huge creature.)

Print one of everything except the sword, which comes in 2 halves. Legs should be printed upside-down. You'll still need supports for a lot of the pieces but it should be much less than trying to print the whole thing as one piece.

Tolerances are pretty much zero, so should be glued with a solovent (like acetone.)

I printed the head at 0.1mm with a 0.25mm nozzle, the other pieces at 0.15mm with a 0.4mm nozzle.
