I know you can just screw the rims of a hide upside down on the ceiling, which is what I'm trying to avoid since you'd have to unscrew it every time if access is needed. I have ideas ranging from getting more lipped L brackets and putting them right at the edge of the ceiling and flipping a hide over to rest its rims over, with juuuust enough room to lift and slip the hide out if needed. Or have the hide right side up and have a shelf underneath it on drawer tracks so I can slide the shelf out and access from underneath. I'll figure something out when I have the time.
