I made two methods that could work to repair your Hololens. The Notch Method and the Pin Method.
- The Notch Method involves cutting triangular notches into the side of the strap. Printed teeth are then used to hold the strap in place.
- The Pin Method involves drilling or punching a hole through the strap. A printed pin will hold the strap in place.
You must decide which works for you, or which tools you have on hand to appropriately finish the job.
