20 cm Antenna Stand STEP Design

I need a clean 3D model of a 20 cm-diameter stand that will securely hold six circular antennas. The layout is a circular pattern with one antenna centered and the remaining five evenly spaced around it. Each of the six recesses must have its own unique circumference and depth; I’ll provide the exact measurements as soon as we start.

Key points
• Deliverable: a single, well-organized .STEP file (my preferred format) that I can pass straight to the machine shop or a 3D-printing service.
• Appearance: plain—no text, logos, or other branding.
• Material isn’t locked down yet, so keep wall thicknesses and fillets practical for either machining or common print plastics.
• Overall height, base thickness, and any fillets or chamfers should balance stability with a tidy, professional look.

Scope
I’m looking for a solid, parametric model rather than a quick mesh. A tidy feature tree, named dimensions, and configurable hole sizes will let me tweak tolerances later if needed. A brief PDF or image snapshot that shows top, side, and isometric views will help me verify the design before sign-off.

If you’ve worked on similar multi-antenna holders, or you’re comfortable designing jigs, fixtures, or test stands in SolidWorks, Fusion 360, or Inventor, you’ll be a great fit. Please include one or two examples of past STEP files or screenshots so I can see your modeling style.

I’m ready to get started right away and will respond quickly to questions about the exact hole diameters and depths.
