Delta Frame Column
One of three 20 mm OD × 150 mm hollow columns for the 'SG90 Mini Delta Pick-and-Place Robot' kit. Each column sets the fixed distance between the base plate and the servo top plate. Each end has an 8 mm solid plug with a 4.0 × 6 mm bore for an M3 brass heat-set insert, and is fastened with an M3x10 SHCS through the plate. A 0.6 mm chamfer on each end lets the column seat fully in the plates' 20.6 mm locating recesses, and there are three 1 mm decorative flutes.
