Super Strong Ceiling Hook

thingiverse

A beefy and attractive hook for a million uses, such as hanging bird feeders. Designed to use whatever screws you have around the house, #10 pan head or wood screws. Countersunk hole hides the head and guides the screw home. Ceiling_Hook_1 is most attractive due to its symmetry, but doesn't print well because of overhangs in both orientations. Also it's hard to get a screw into it. Shown here in case anybody wants to improve on it. Ceiling_Hook_2 is asymmetric and designed for printing. Overhangs are reduced to printable angles. The loop is offset so a screw goes in easily. Still suffers from bridging defects, and has a weakness at the intersection of parts. Ceiling_Hook_3 adds reinforcement to the intersection of parts, and reverts to a circular base. Unsupported overhang is still a minor issue, but the hook is super strong. I recommend this version until I or somebody else has a Eureka moment and improves it.
