Based on the Sewer Rats by -Taylor- my son Sandro built this variation. Together we modelled it with MLCad today. Afterwards I did the render and made the instructions with LPub.
Here are the instructions for my microscale Tachikoma. You will need: -2 Inverted dome piece thingies -1 Round tile (2 x 2) -1 Stud -1 Jumper plate -2 Clone trooper rangfinder thingies -2 Binoculars -2 Right minifig arms -2 Left minifig arms -2 Bits of pneumatic tubing (roughly 1 mm or so long) Enjoy your tiny Tachikoma!
