Here's a little robot toy I designed. All of the limbs and accessories are customizable and can fit in any of the 2 mm ports on the torso or hip sections. The limbs are all identical(no right or left leg/arm) so you just need two of each limb file. If the limb pegs don't fit in the holes just carefully sand/chop off some of the sides(the reason why the pegs are plus shaped in stead of cylinders). There is a .05 mm tolerance of the peg and port. I'll upload new accessories and body designs in the near future.
I've been test printing these and the best orientation of all the joints is printing the pegs so that the are parallel to the build plate and printing the whole thing with supports.
