Here is my first self-made 3D printed mecha all assembled. Made from 33 parts and it is approx 6.5" tall. Not articulated... maybe for the next one? I used my new Afinia H-series printer. It's an entry level printer so the resolution isn't great, but isn't bad (.15mm).
Here's my concept art for the piece
and the 3D model I made with Blender
