Mechanical Arm

thingiverse

So this is a mechanical arm I 3D printed for the Halloween of 2018. The bracers, upper arm, and pauldron will likely only fit me because it was custom designed, but it's a good place to start if you're interested in 3D printing the parts. Skulls from: https://www.thingiverse.com/thing:2396869 Adeptus Mechanicus Emblem from: https://www.thingiverse.com/thing:1098997 Printed each part separately, then sanded down to fit. Tolerance not included for the lower piston, print at 95% scaled in x and y directions, assuming you are printing the part vertically Also, I had a significant amount of difficulty with the gears(nuts shaped like gears), fitting to the bracers/ upper arm, so I scaled them to 105% when printing. I suggest doing this, though if your printer has more precision than an Ender 3 on 0.1 mm layer height, feel free to try printing at 100%, though I'm not sure it'll have enough tolerance :) Key for the hand: B- base, basically the back of your hand T- thumb p- pinky po-pointer r- ring finger m- middle finger they're numbered in such a way that 1 is closest to the back of your hand, and 3 is the furthest away Printed pauldron at 160% because 100% was too small for me
