Bed levelling nuts for Anet A8

thingiverse

Update. I just realized my frame wouldn't tolerate zero tolerance nuts. And the bushings on top of M3 nuts add about 1/4 inch to the height of the bed. One trip to the drawing board and I reduced the diameter of the nuts, adding tolerance to the inside of the upper bushing to completely absorb the M3 nut. This is a remix of the Bed Level Upgrade by Malcy. I found the original didn't fit my Anet's butterfly nuts – they are fatter where the nut meets the wings. The mod adds a 2mm radius easing on the interior for more room. The bushings for the springs remain unchanged. 50% infill might not be necessary, but I wanted to make sure. It might be helpful to put a washer between the plastic nut and the bottom of the H-frame. Per Malcy's note, you should de-tap the hole in the H-frame with a drill bit.
