I get splinters, and the real fine metal ones are a pain.   Cant do much other then cut slits in your skin near them until you can get at them. Anyway I have a collection of xacto blades and tweezers and wanted a home for them so I made on.    

I use a hinge we have at work MS20250-3  and trimmed the edges down to glue into the slots in the model.   you could probably use a print in place hinge and glue to back.   Haven tried it yet but like [https://www.printables.com/model/355434-low-profile-print-in-place-60mm-hinge](https://www.printables.com/model/355434-low-profile-print-in-place-60mm-hinge)
