About this 3D model

After two years my printer started making squeaking noises and wrecking prints. It turned out the bed sometimes bowed and hit the Y motor shaft. I'm replacing the Y-bar ends with the longer version to lift the bed. In the process I thought I'd try out the flower nuts I bought from DX. Search - Brass Flower Screw Nut - other places have them too. Full title - Jtron M3 Brass Flower Screw Nut / Die Cast Screw Nut / Mosaic Screw Nut.
