It´s a frog on top of some branches.
Sculpted in Blender
You have to print all the parts on the proper colors and glue everything afterward.
The model on the pictures was printed with 0.2mm layer high, but I recommend 0.1 or less, for finer detail.
As the weight of the "branches" part is all towards the same side relative to the base layer, adhesion to the printing table is paramount here. Use a raft, if you have problems.
Start your print from the eyes and pupils. If your printer has issues on those parts (they are quite small), scale everything up as necessary.
I've added two versions of the frog, one in a single piece (you´ll need a lot of supports here) and other divided into two parts (bottom and up). In the latter, only the upper part needs a bit of support.
Let me know if you have questions. Regards!
