Anet A8 Platform

This is an aluminum one piece platform that incorporates an attachment point for a cable chain for the hot bed and thermistor wires.

The attached file is a .dxf file and is suitable for laser or water jet cutting.

I made mine from 5mm 6061-T6 aluminum. The corner holes are oversize rather than threaded and receive an 8mm counterbore to keep the leveling springs centered around the m3 screw. I also ran an m3 nylock nut on the m3 adjuster screw up tight to the heat bed. That centered the spring at the top and prevented the screw from spinning in the bed.

I now adjust the bed only from below and it requires very little tweaking. This way I do not have to remove the glass bed cover to make adjustments. I use the knurled bed adjustment knobs here https://www.thingiverse.com/thing:2138298

Additionally there is the drag (cable) chain restrainer that snaps on over the platform frame edge. This is necessary to keep the cable chain from moving above the bed when moving in the -Y axi
