These spinnerets are of a common orb web weaver that I have yet to identify. The closed nature of the spinnerets in these images is unfortunately more common than the more open variety that show more silk spigot details. Luckily some of the silk spigots are easily visible in the upper two organs. A few additional in the lower left of the spinneret in the higher magnification number 2. My apologies for the stray hairs.
