Instruction / Post Processing
To prevent the base of the arms falling over, I recommend printing this with a raft. Can be printed full size or bigger (If you are printing at normal size, and the joints are all welded, scale it up and try again), however it might not work if you scale it down too far.
Once printed, use a craft knife or something with a sharp, flat edge to gently take it off the build plate. The arms and legs might need to be pushed a little but should then snap into place and start moving.
If you print in PLA plastic then you should file or sand the top of the column that connects the head to the body, so that it fits into the hole underneath the head. This happens because of PLA shrinking so much, but it might also happen with ABS.
Can be printed in any material but it probably won't work with flexible filament. Once printed, depending on the material and infill percentage, but even with more brittle materials, such as Wood fills, it still is extremely strong and durable. It also doesn't require any support material.
