Parametric coat hanger V2
by jsadusk, published
Same concept as my last hanger except this one actually works. I changed the snap pins to friction fit pegs inspired by thing 19058.
From the original: I've been wanting to make printable versions of common household items, and I've wanted to experiment with printing snap together objects that are bigger than the print bed. So, here's a coat hanger in three parts. Some of you are probably saying "I can get 10 hangers for a couple bucks", and you are missing the point. This is an item that people use in large quantities without really thinking about, that they're reliant on the mass production of huge factories to create, that break often and have to be replaced, and could probably stand to be customizable. This is breaking your dependency on mass produced products for everyday life needs.
Updated: Made the friction pins a bit tighter of a fit. If you've already printed it and they came loose, download again and try.

Print one of hanger_hook.stl and two of hanger_side.stl. If you'd like to regenerate these from the scad, at the end of the file should be a function call to render either the hook or the side. Uncomment the one you want. At the top of the file are all the parameters. You can customize the height, length, bar diameter, and the diameter of the bend in both the corners and the hook. Don't worry about angles or alignment or anything, it should recalculate all of that.
Once printed, flip over one side and push the friction pins into their respective holes on the top and bottom of the hanger. For the top joint, fit the small peg of the hook in the channels of the two pin plates. The pins should be a tight enough fit that you will need a pair of pliers to get them in, but once in they will stay there.
This is currently sized for printing on a Mendel bed. If there's demand I can break it into more pieces for printing on a Thingomatic. It may fit on a Replicator with slight scaling.
