He3d K200 Heat Bed Adjustable Sprint Mount

thingiverse

The K200 head has a small piece of acrylic that attaches to the corner frame, securing the adjustment bolt. This design falls short in some areas. While this modification isn't perfect, I believe it is an improvement over the original. A better design would likely attach to both sides of each corner piece. The source component features a recessed hole for a 4mm washer and another recessed hole for the 3mm nut. Key changes include adjusting the distance between holes (mounting to adjustment) to meet the HE3D's needs, rather than those of the Anycubic, and recessing the spring hole to prevent the spring from moving. The openscad source file is included, allowing you to adjust the clearance of the nut, spring, and bolt holes as needed for your printer. I recommend not altering other sizes, as this may yield unexpected results.
