The idea is taken from a transformer Q-MECH Aggy produced by wazzup family. I created my own project based on the photos of this toy. The main difference from the original is the transformation mechanism when pressing the tail (see video).
Both ABC and PLA were used in producing. The details which include a letter in the title are alternative variants of making: whith farher merging from elements or with my supports.
The following external screws were used during fitting:
M2 8 mm 10 pcs
M2 10 mm 10 pcs
M3 12 mm 5 pcs
M3 25 mm 2 pcs (flat head)
And 3 springs, their geometry depends on what do you have.
