Zurn Wilkins 720-A Pressure Vacuum Breaker repair kit: spider assembly, o-ring, canopy

Needed to repair my leaking anti backflow valve on my irrigation system because the so-called spider assembly got damaged. The repair kits can get quite expensive so I thought I'd design my own--at least the non metal components. The spider assembly is the check valve section of the Wilkins 720-A anti backflow device. The design is for the three-legged plastic seal carrier. Print it in PETG, ABS, or ASA using grid supports in the orientation shown in the screenshot. The o-ring is to be printed in soft TPU. Original sizes are likely in mm but the knockoff chinese repair kits list the rounded dimensions in inch, so I am providing both options just in case. I'm also providing an easy to print canopy redesign just in case.
