3D CAD Design for Speaker-Stand Concepts

Pinscher Group is seeking an experienced CAD/product designer to develop two existing sculptural wooden speaker-stand concepts into accurate, manufacturing-ready 3D CAD.

The designs are already established and reference drawings/renders are attached. This is not a ground-up design project. The goal is to preserve the sculptural appearance while refining the geometry for real-world manufacturing.
Project requirements:

Advanced organic/freeform surface modeling
Approx. stand height: 24.4 in / 620 mm
Semi-universal top plate for high-end bookshelf/monitor speakers
Primary sculptural structure manufactured from wood
Evaluate the best construction method: one piece, two pieces, or another practical configuration
Optimize for CNC machining, strength, material usage, assembly and finishing
Concealed speaker-cable routing
First prototype approximately 1:4 scale for 3D printing
Required deliverables:
Native/editable CAD model
STEP/STP
STL
Separate component files as required
Assembly/exploded view
Basic dimensioned manufacturing drawings
1:4-scale watertight STL for prototype printing

Fusion 360, SolidWorks, Rhino or comparable professional software is acceptable.

Please quote Concept A and Concept C separately. We will most likely select one concept for the initial project.
In your proposal, please include:
Fixed price for each concept
Estimated completion time
Number of revisions included
CAD software you will use
Your proposed approach to CNC construction/part division
At least one example of previous organic/freeform surface modeling, preferably furniture, wood products or CNC-manufactured components
Important: We are specifically looking for strong organic/surface-modeling ability. Please do not bid based only on conventional mechanical CAD experience.

If the first project is successful, additional speaker-stand designs will follow.
