Unique Silicone Shower Caddy Design

I run an Australian bath and body brand. I need an original product design for a wall mounted silicone shower caddy, similar in function to existing organiser products on the market (holds bottles, has a pocket or shelf, mounts to a wall), but with its own distinct shape and silhouette that isn't a copy of any competitor's design.
Reference for the type of product category, not to be copied: https://au.konsilee.com/collections/all-products/products/the-kendall-shower-caddy
What I need:
2-3 original concept sketches or digital renders of a silicone shower caddy shape
The silhouette, outline and pocket structure needs to be genuinely different from the reference above and any other existing market products, this must be an original design, not a variation of it
Consideration for manufacturability, needs to be producible by a silicone injection moulding factory, not just a nice drawing
My logo embossed into the design, similar to how competitor products emboss their branding directly into the silicone (I'll provide the logo file)
Final deliverable must be a STEP (.stp) file, suitable for handing directly to a manufacturer for silicone mould tooling
Suggested wall thickness and draft angles included, appropriate for silicone injection moulding
Functional requirements:
Wall mounted, suction or adhesive backed
Holds 2 or more bottles upright without them tipping
A pocket or shelf structure for smaller items, soap, razor, loofah
Ribbed or textured surface for grip and water drainage, similar function to reference, different execution
Roughly [fill in your target dimensions] in size
Suitable for a shower corner or flat wall
Not required:
Full brand identity or logo design, I already have a logo, this is just placement into the 3D model
Please include in your application:
Examples of past product design work, ideally physical products that went to manufacture
Whether you've designed for silicone or rubber moulded products specifically before
Confirmation that you design in CAD software (SolidWorks, Fusion 360, Rhino, etc.) and can export STEP files
