Flapper Socket Display Stand
This is the display foot for the 'SG90 Scotch-Yoke Flapping Wing Rig' kit. The base is 140 x 100 mm with a 6 mm stiffening rib and lightening windows. The socket block is 96 x 17.5 x 22 mm, with an 85.0 x 5.5 x 15 mm slot that the spine plate's bottom tongue drops into. Two M3x25 bolts with M3 hex nuts lock the spine in place. They pass through 3.4 mm holes at X ±30, and the nuts sit in pockets (5.7 mm across flats) on the back wall.
