MagicD ANET-A8 build plate support

thingiverse

the MagicD ANET-A8 (from Amazon) is a fairly decent variation of the ANET-A8 configuration that uses 2040 extrusion for its' structure ... decent, except for the yaw support of the build plate around the Y-axis ... they use a wheeled trolley design to translate the Y-axis, but they build the trolley across the 20mm width of the 2040 extrusion, which results in the build plate being very unstable (wobble-ly) in rotation about the Y-axis ... this fix adds support rollers to the underside of the build plate on both sides of the X-axis 2040 extrusion ... materials required: 2 x replacement screen door rollers (with bore that fits a 10-32 screw as an axle) ... 2 x 10-32 x 1" screws with nylon lock nuts ... 2 x 5x12mm screws ... 2 x 5x26mm screws ... 4 x 5mm T-nuts note: the screen door rollers are mounted to the support brackets via a cam sleeve which allows the wheel to be raised or lowered to achieve the proper height for support under the build plate ... when mounting the support bracket, first tighten the shorter 5mm screw to lock the bracket in place on the X-azis 2040 extrusion ... then rotate the cam to raise or lower the support "wheel" and tighten the longer 5mm screw to lock the cam in position
