3D-Printed Speech Therapy Aid

I need a product designer who can turn a clinical idea from my speech-pathology practice into a simple, safe, and truly useful 3D-printed tool.

Here is how I see the workflow:

1. Discovery
• Meet with me online, hear the specific task I’m trying to solve, and talk thorough the concept.
• Translate those clinical insights into clear design specs—above all, the device must be easy to handle and use for speech pathologists during sessions.

2. Concept & Prototype
• Produce an initial CAD model (STEP or similar) plus print-ready STL files that work on a standard FDM printer.
• Optimise wall thicknesses, rounded edges, and tolerances so it prints reliably without support wherever possible.
• I will print and trial the prototype in real sessions, gathering usability notes and wear-and-tear feedback.

3. Iteration & Final Files
• Refine the geometry based on that field feedback, improving durability and ergonomics.
• Deliver the updated master CAD along with labelled STL files ready for future prints.

Acceptance criteria
• Prints cleanly on a Bambi P1S
• No sharp edges; all patient-contact surfaces have ≥1.5 mm fillets.
• Full assembly (if any) completed in under a few minutes by a clinician using only their hands—no tools.
• Final files open without errors in Bambu software.

If you are comfortable and creative and feel you are able to support, let’s create this together.
