Parametric CAD + STEP/DXF for Simple Welded Frame w/ Fan Panel (Bed Cooling Cart)

Goal Turn two mockup elevations + my constraints into a shop-ready CAD package a fabricator can quote. The product is a simple welded frame on casters with a front fan panel and a separate bin behind it. Hard constraints (do not change) Overall envelope: 54″ W × ≤12″ D × 60″ H Frame: 1″ square-tube on casters Front panel: included; 4 round fan cutouts; fan centers at 48″ from floor Bin: included as a separate part (open-top wedge behind the panel) Deliverables STEP (AP214) assembly with separate solids named: Frame, FrontPanel, Bin, Shelf, Casters DXF for the front panel (single perimeter + 4 circles; clean geometry) 1-page PDF showing overall dims (54/≤12/60), fan center height = 48″, panel size/thickness, plus note: Unless noted: Linear ±1/16″, Holes +0.010/−0.000″, Angles ±1°. Native CAD file (Fusion 360 / SolidWorks / Onshape) with clearly editable dimensions (parametric preferred) Reasonable assumptions (unless I specify otherwise) Tube: 1″ × 0.065″ steel; Rails: bottom + mid (at fan height) + top Front panel: ~2 mm sheet (steel or aluminum) Bin: thin-wall visual; ≥1/4″ clearance from frame Casters: generic plate casters (no exact bolt pattern) Milestones M1 Block-out (2–3 days): posts/rails, panel w/ 4 holes, bin wedge (screens for approval) M2 STEP preview: quick measurement check M3 Final package: STEP + panel DXF + 1-page PDF + native CAD (payment on acceptance) Acceptance checklist STEP opens with separate, correctly named bodies Measures: W=54.00″, D≤12.00″, H=60.00″, fan centers=48.00″ DXF: one outline + 4 circles, correct units, no duplicates PDF shows key dims + tolerance note Please include in your bid CAD tool + whether model will be parametric/editable 1–2 examples of welded frames/brackets you’ve modeled Fixed price and lead time; any DFM suggestions (tube wall, panel thickness, edge distances, finish) IP Work-for-hire. I own the source files and deliverables. Apply tot his job
