Hidden hinge. (For Lack table)

This is part of a modular system i'm creating for a stack of Ikea Lack Tables (https://www.thingiverse.com/thing:2880834), to contain my 3d Printer and related bits.

I couldn't find a good enough design for a strong 3d printed hidden hinge, so a made a thing.

The hinge could be used for other doors and whatever that needs a sturdy design.

This is being revised as I construct the Tables, with other modular parts like leg extensions.
