Prompt

Make a fork yoke as a single solid. The base block is 80mm × 40mm × 12mm, centered in X and Y with its bottom face on the XY plane (x in [-40, 40], y in [-20, 20], z in [0, 12]). Two vertical tines (fork arms) rise from the base. The left tine is 14mm × 40mm × 45mm at x in [-40, -26], y in [-20, 20], z in [12, 57]. The right tine is 14mm × 40mm × 45mm at x in [26, 40], y in [-20, 20], z in [12, 57]. The gap between the tines (x in [-26, 26]) is open. Through both tines, drill a coaxial cross-bore of diameter 18mm whose axis is parallel to X, centered at y = 0, z = 44.5, passing through the left tine (x in [-40, -26]) and the right tine (x in [26, 40]). The cross-bore removes a cylindrical channel of diameter 18mm from each tine; the open gap between the tines is unaffected. Output a single solid.
