Complete a Three.js project that is updated on users input

Introduction:

Based on a small prototype, I'm looking for a three.js developer to finalize a job.
The 3d model has to be integrated into a configurable product page and has to get updated depending on the user's input. In the prototype, a 3d model is imported and contains elements to create a visual version of the user's input.

Requirements:

- Review the prototype on the code quality.
- The user can configure around 8-10 options for his product; these options are set in the model. Implement these options as specified.
- Detail requirements are available and will be provided as a ticket.
- The product configurator is based on jQuery and already exposes the user's input.
- Add the three.js model into the existing code and update it according to the user's input.
- A staging environment is available for development and testing.

I'm looking for a skilled developer to work closely on this project.

Prototype:

- Set any number to see how the length changes
- Set the second and/or third input field to 0 to see how the model changes.
