This time it took longer because I resorted to rough sketches and imagination in terms of the design. Used various bits and bobs from around the web for inspiration, but it's not a blatant copy of any particular design. It's actually quite challenging to come up with a mech design, but eventually I came up with something I like and, hopefully, you'll too.
I called it AH-KU MKII (Autonomous Hunter-Killer Unit, Mark 2) - dubbed "Cheetah" - as speed, camouflage and agility are what brings it to close quarters combat at which it excels. Being caught out in the open though renders it almost helpless.
Print big for FDM, print at around 50mm tall for DLP.
Checks out OK from Netfabb.
Will require a bit of sanding as the tolerances on the parts are extreme to say the least. But a minute with sandpaper and you'll be OK.
Blender all the way, as usual.
If anyone's interested, the presentation screen was made using Substance Painter.
