Simple Concealed Hinge for Folding Table Tops / Panels (Low-Profile)

This is a more straightforward sibling to my 180° Stealth Concealed Hinge

I designed this version to be easier to print, easier to install, and very practical for things like folding table leaves, fold-out work surfaces, portable desks, lids, or any two panels that need a clean look with the hinge hidden inside a pocket.

The hinge mounts into a recessed cavity, so from the outside you only see a neat seam between the two panels.

Key features

• Concealed / low-profile installation (clean exterior)

• Simple mechanism (fewer parts than the stealth hinge)

• Designed for flat-folding panel applications

• No supports needed (prints cleanly)

• Uses common hardware: 2 hinge pins/rods + 4 mounting screws

Printing recommendations

• Material: PETG recommended (tougher, better long-term wear). PLA works for light-duty / prototypes.

• Layer height: 0.2 mm

• Perimeters: 4+

• Infill: 30–50%

• Supports: none

• Print the parts flat as oriented in the STL.

Tip: If your printer tends to print holes tight, enable hole compensation (or lightly drill/ream after printing).

Hardware needed

• 2× metal pins / rods with 3mm diameter  and 30mm length - for the hinge axes (use the diameter that matches the model)  - Locating Dowel or Cylindrical Pins

Installation notes

• The hinge is meant to sit in a pocket/recess. Use the model to size the cavity.

• Leave a small gap between panels so they don’t rub during rotation.

• For larger/heavier panels, use multiple hinges spaced evenly.

Assembly Guide

• Blue and gray parts are 3D printed

• Black parts are Ø 3mm steel pins, it is necessary to ream the holes for the steel pins to an exact 3mm diameter

• Ensure you have the correct pin lengths
