This model is my 3D personal editing creation on a Gundam like a lego style, but is not a lego e do not have similar size.
I have print this model with white PLA 1,75 with normal settings of Cura, use a support Option for best result printing.
The model is playable without a glue, simply use a normal PLA 1,75 filaments, just cut a size if you prefer and insert into hole present in the internal shell for fix it.
If you like is possible to print with different color of PLA for customization or paint a model with color like a photo.
The size of final assembled model is: height - 11cm; length - 7cm; depth - 4cm.
