It has lots of issues: the general look says it's a Boba Fett helmet, but the details are all wrong (cheeks, dome, mandibles, ears and so on). It looks to be a poorly made scratch build helmet.
You can freely download most of my models on Shapeways (you'll have to create a free account), but my helmet is not that accurate. As BudaFett said, MinuteFett sells on Etsy 3D models made with scans of the lineage helmet.
thanks for the advice Ive actually taken the plunge and ordered a Bobamaker VX ESB , i like the idea of fibreglass rather than PLA or resin and there no issue with accuracy
