These are the plastic connectors you get when you buy plastic shelving of this type. If you have this style shelving units and need more connectors or want to add a simple hook, this is for you.

-- Connectors print right-side up without supports, and brim shouldn't be needed.

-- Hooks print right-side up with supports (tree worked great for me), and brim shouldn't be needed.

I have not tested the strength of the hooks printed right-side up, but they seem fairly strong. If you want something stronger, it might benefit printing the hooks on their side. This would result in more supports.
