This case is designed to fit the Miyoo Mini PLUS handheld. It works as a protective case, with a secure latch and a simple hinge mechanism. When used as a grip, the Miyoo PLUS slots into place securely and is held in place by the ridges on the back of the handheld locking into tabs on the case. 

If printing for yourself, use a piece of filament with a dab of glue on either end as the hinge, or #16 brad nails will work as well. 

The Mini PLUS can also rest in the opening vertically to use a display stand when sitting on a shelf, etc.  

No supports needed, print each half flat-side down, with 100% cooling at layer 3 for the best details with the design inlays. I recommend cutting and fixing a piece of adhesive-backed felt (also called “jewelry box liner” or “drawer velvet”, can be found at craft stores) to protect the screen from debris scratches and for the perfect fit.
