Anti-Twist Exoskeleton for Anet A8

thingiverse

You need: 1 M8 threaded rod (~34 cm) 4 M8 nuts 2 printed parts optional: M8x1.5 tap (but could be tapped with the threaded rod). Anet A8 A simple anti-twist exoskeleton for the Z axis, that could benefit XY as well. I really loved aeropic's designs, but 6mm threaded bolts are not that stiff. For the Z-antiwobble exoskeleton 6mm is the only option, but for the anti-twist 8 mm is not a problem. So I designed this part for the holes on the vertical acrylic side panels of Anet A8. It's a really simple part and a simple mod. It acts like a torsion bar in a car suspension, so I assume that a 90 degree rotation between the plastic parts could benefit both XY, but I greatly doubt that this would be observed during printing. Nevertheless it's another mod to make the printer a little bit stiffer, and as overall cost is around 1 euro, it doesn't bother me being there. In the one I've printed I tried 2 dimensions, the one uploaded is the one with the right tolerances. I used HIPS plastic (High Impact Polystyrene) as I want to get rid off due to warping issues. PLA would be the same. I love simple designs, so enjoy!
