Topology Optimized Anet A8 Rear Frame Brace
thingiverse
This is a topology optimized rear frame brace for the Anet A8. It supports the Y motor when you tension the Y belt. I advise you to position the print likewise on the photos, if you do, it's less likely to break because of the layer direction, and actually prints faster. 14 sized wrench should fit there for the M8 nut just enough to hold it in place while thingthening from the other side. I printed this with 0.2mm layer height, 35mm/s print speed, 1-1.2mm wall thickness and 40-50% infill (I used octet in Cura) should be enough. 8mm Brim and Supports are needed. (The pictures look a bit off, because Thingiverse deformed them all)
