The model you can see on the pictures was printed with PLA 1.75 mm silver filament on an anycubic I3 mega printer with 0.1mm layers (printing temperature 200°C - base plate temperature 60°C). The scale of the model is about 1/30. In order to assemble the parts, you're gonna need 19 CHC Screw M3 x 10 (ISO 4762) and 19 H Nut M3 (ISO 4762) as shown in the instruction manual. Feel free to contact me for further informations and your feedback.
