The prompt
Design a professional commercial-style Y-axis dual linear shaft end support for a compact 3-axis CNC. Requirements: - Supports 2 parallel Ø12 mm round linear shafts. - Lead screw runs centered between the two shafts. - Rigid mounting to an aluminum CNC frame. - Parametric design in mm. - Use proper shaft bores, bearing seat, mounting holes, structural ribs, fillets and chamfers. - Symmetrical, clean industrial CNC design. - Thick enough for PCB milling and light aluminum machining. - Designed for 3D printing, with practical print clearances. - No decorative/toy-like geometry. Make it look like a real commercially manufactured CNC motion component, not a simple hobby bracket. Keep shaft spacing, lead-screw diameter, bearing dimensions and mounting-hole spacing as editable parameters because the exact hardware dimensions will be provided later. Output a STEP model and STL, and inspect the geometry for symmetry, alignment and interference.
