Judges/Everyone please watch my submission video below, which shows how I generated the model with photogrammetry using Autodesk ReMake (https://vimeo.com/190468054)

Workflow

I decided to use the turntable approach for taking the photos.  For easy and accurate rotation, I designed a turntable with worm drive and also custom rigging in Autodesk Fusion 360 for mounting the headphones on the turntable.  Without the rigging, the earpieces naturally collapse against each other. The rigging keeps the earpieces spaced apart and suspended above the turntable platform.  I have uploaded my turntable for everyone to try here: https://www.myminifactory.com/object/25004

The headphones have many smooth, shiny, black surfaces which are not ideal for photogrammetry.  To deal with this, I applied cornstarch over the surface, which adds color variation and a matt finish that allows Autodesk ReMake to generate a clean model. It is also easy to wipe off afterwards.

After the model generated successfully, I used Autodesk ReMake's editing tools to delete the custom rigging and smooth out the surface. 

Lighting and Camera

I used three halogen work lights (2 x 500W, 1 x 250W) with translucent velum paper from the crafts store as diffusers.  The background sheet is a piece of white vinyl from the fabric store.  My camera is an old Sony NEX-5N, set to manual to keep the shutter speed, aperture, and focus constant.  The ISO is 100.  The camera is mounted to a Gorillapod.  I used a remote trigger to ensure crisp photos. 

The Print

I printed the model with an Ultimaker 2+ in white PLA at 0.12mm layer height on a 0.4mm nozzle for good detail.  Print time was about 32 hours at 10% infill.  Seams between the halves were patched and smoothed with a little modeling putty.  The result is a highly detailed, dimensionally perfect replica.

I have also uploaded a few product photos so that you can see just how perfectly the scan captures the details of the original headphones.

Customization

The model is a bluetooth wireless Bose AE2W headphones.  I plan to customize the exterior of the headphones with custom cans that will look awesome.

Thanks for Viewing!
