Create a bearing bracket from this complete coordinate specification, units mm. Base x=-30..30,y=-20..20,z=0..6, XY corners radius 4. Four diameter 5 vertical mounting holes at (x,y)=(+/-23,+/-13). Upright plate x=-20..20,y=-4..4,z=6..36, topped by an upper half-cylinder radius 20 centered x=0,z=36 with axis along Y. Through bearing bore diameter 22 along Y centered x=0,z=36. Add two triangular supporting ribs, each 4 thick along X, centered x=+/-14; YZ triangle vertices (4,6),(16,6),(4,26). Fuse the base, upright and ribs; keep bores open. Round the upright's external front and back perimeter edges with radius 1, but leave bore and rib edges unfilleted. Export STEP and STL. Length tolerance 0.1 mm.
