Laptop display stand and VESA mount. It can be used to raise a laptop when using it with an external keyboard and mouse, or it can be used to attach it to a VESA-100 compatible monitor arm (I'm using it with this one*).
I have only printed the larger one (shown in the pictures). That one should work with 13" and larger laptops. The smaller one should work with 13" and smaller laptops (but has not been printed).
Uses threaded brass inserts for the VESA mount.
