Delta Servo Top Plate
A 5 mm thick tri-lobe top plate for the 'SG90 Mini Delta Pick-and-Place Robot' kit, about 161 × 162 mm. Three 32 mm column pads at radius 75 mm have 20.6 mm × 1.5 mm locating recesses on the underside and 3.4 mm holes for M3x10 SHCS into the columns' heat-set inserts. Each of the three servo lobes has a pair of 3.4 mm slots, each giving ±4 mm of radial travel, so the SG90 cradles can be adjusted on M3x10 screws. The lobes also have an arm-swing notch, and the hub has a 30 mm wiring hole with a zip-tie slot pair.
