Anet A8 Y-axis anti-rattle

thingiverse

My A8 has quite a noisy Y-azis. The 8mm holes in the perspex front and back are fractionally over-sized (if not, assembly would be tricky). Here is a set of clamps which can replace the tear-drop perspex plates that retain these rods. Use an M3x12 cap-screw to tighten them, and the original M3 bolts to secure them. No need to over-tighten. Although I didn't observe any significant reduction in the movement of the bed (using a dial gauge, about 0.2mm) this movement is now all from flexing of the rods, not movement. So, it's quieter and maybe smoother at higher speeds. STL for each corner, or the whole set. There is a mounting for the Y-axis limit switch, and a version without this too. Also added a Z-axis version, which is quite a bit longer. I made the main hole a little over-sized, for easier fitting, but this shouldn't matter. Use less than 100% infill to make sure it's flexible. 24 May 2017 Updated to add clearance for wing nuts. It is still possible that the wing nuts catch on this clip, so it's better to replace them with a normal nut. Depending on how you have the Y axis arranged, and the length of your rods, you might lose a couple of mm of Y travel. With this mod, you can increase the Y offset front/back slightly to compensate.
