Surface Pro 3 Hand Strap

To create this, a 1-inch belt and a "strap adjuster" like this are required: https://www.thingiverse.com/thing:2613356 I recommend finding a nylon strap, ideally repurposing one from a damaged backpack or bag. Nylon straps can also be purchased individually or in bulk. I used cotton, which was a tight fit. You have the option to use supports, and if you're lucky, you can set it to "touching buildplate only" for some support under the bridge. Alternatively, you can choose not to use any supports and rely solely on bridging. Using a thinner strap will make threading easier. There's limited space for the camera, so printing two bottoms (or tops) is also an option. The top one works well with the bottom screen in portrait mode, leaving sufficient room for the windows button.
