I designed this around my Microsoft Surface Book 2 - 15 inch model. It should work for the Book, Book 2, and Book 3 for both sizes. While it was designed to work in landscape orientation, it seems to work fine in portrait too.

This is an early design of a product that I plan to sell on my Etsy shop at https://www.etsy.com/shop/MajorParus

Use PLA+ (PETG is untested but may work also). I have great success with PolyMaker PLA+ and Overture PLA Pro.

Please let me know if you have any questions.
