I haven't printed this yet, but I've preview printed it in the UP! software and there are no errors, but please make sure you check on yours.

It will need a strap added to the handle, philips head screws, cables for detailing and various graphics, but there are plenty of reference photos on line.
The dimensions for the full size Motion Tracker are 28cm, 22.5cm, 18cm.
