This is a hook/hanger for a Lodge LCC3 Logic Combo Cooker (http://www.amazon.ca/Lodge-LCC3-Logic-Pre-Seasoned-Cooker). I believe it will work with other Lodge cast-iron skillets, but have not tried it. I included a small test object which is a cross-section of the hanger body. If it slides through your skillet’s handle then the hangar will work (took me a few iterations to get it right…)
This hanger is designed so that it is very difficult for the skillet to be accidentally bumped off the wall. The skillet has to be be rotated to about a 45-degree angle away from the wall, and then lifted upwards. Cast-iron skillets are heavy - use two hands!!
The hanger contains two inset 45-degree-angle screw holes, which will fit a #10 round-top screw head. If you are hanging a heavy cast-iron skillet from this print, you absolutely want to put the screws into a stud (mine are sunk into a support post for a ceiling beam). Because the holes are angled, the screws need to be quite long - 2.5 inches will make it a decent way through the hanger and a sheet of drywall.
I have included a jig I used to drill 45-degree pilot holes for the screws. I used a clamp to keep this jig level while I drilled, see the attached photos. This jig is a remix of http://www.thingiverse.com/thing:402531. Once you have drilled the pilot holes, just put the screw through the hanger. You probably want to hand-tighten the last few turns to avoid shattering the plastic.
I printed this on a Replicator 2 with PLA, Standard print quality, but with 30% infill, for strength. Support is necessary, I used MakerWare support to provide the best print quality on the bridges. There is a mouse-ear-style single-layer sheet around the base, this is to minimize warping and will slice off with a knife.
If you are concerned about strength/durability, it would be better to print the hanger such that the holes point upwards (or downwards). This way, the load is orthogonal to in-layer filament loops, rather than parallel to them, so delimitation will not result in catastrophic failure. However my skillets have been hanging for several months with the orientation in the file. I stress-tested by pulling downwards and didn’t observe any flexing, however it is possible that the small front-clip part of the hanger could be broken off by pulling forward instead of rotating upward.
