I've just uploaded a model designed to help get the most out of a Next Engine laser scanner. Not many people have a Next Engine, but the principals the tracker is based on apply to many other types of scanners, so this should be of interest to anyone involved in 3D scanning.

The Scan Tracker works by creating an array of reference points around the object to be scanned. Those shapes will be included in the scan, and during alignment this will help "lock" the scans together accurately. Precise alignment is one of the most important parts of creating high quality scans.

It is also especially helpful when you are manually gathering scans from different angles, by giving clear features to place reference points for your initial alignment. It has five larger spherical points that are intended to be captured from both sides, matching distant features around the object. I recommend using 10 "slices" for your scans. If you are manually operating the platform, the points will help you keep track of your position.

This version is hollowed out to reduce the price. If you have your own 3D printer (with a 6 inch build platform) you can download and print the solid version for free. It is available in STL and STEP on Thingiverse.com Here.

Thanks. I'm also pleased with the shape. It reminds me of an undersea creature. The many rounded corners are part of what makes it so effective. Sharp inside corners and crevices are the hardest thing for any scanner to capture.
