its actually very simple and very easy to asemble. sorry just seeing this. 3mm screws is what i use with nuts m3*10 m3*12 and m3*25 are the screws i use. i will say the feet you will need to trim some off the leg bottom to get them to slide in properly. use an excato knife carefully and shave both sides off a little. m3*25 through the batter and then the leg to the foot.
Overall, solid but flaws. One acknowledged but not fixed is the fit of the feet to the legs. Also, the center foot does not quite come down t the surface.
The outter legs yes that was a Design flaw. i find if you scrap a tad off the insert where the screw is at with a Knife it works okay. the Center Leg comes down only when he is Kicked back. not standing idle upright,
Very cool. I'm building a full-sized astromech and would love to have a matching 3D printed companion. Would definitely love to have the "standard" color scheme and will follow to watch for it. Thanks! ;-)
