This hanger was requested by a friend who is very environmentally conscious. I thought this was a great way to recycle 2 bottles while utilizing the TOM's capabilities! A design similar to this by Chinese designer Xuan Yu inspired this thing's creation.

One thing to note is that the holes to accept the threads to the bottles are not threaded. A compression fit seems to work well enough.

This thing is part of a final project for CPSC 183 Technology and the Law with Prof. Brad Rosen at Yale University. The idea of this project is to ask friends for ideas for physical objects that they would like to have that could be printed on the Makerbot TOM. I have designed them, printed them out and given them to the people who requested them. I also have uploaded them here to Thingiverse to add to the library of physical objects that people find cool, useful, or just plain fun!


Print and clean. I needed to use a Dremel tool to cut the threads off of the bottles I was using and a compression fit worked great! Just make sure the fit isn't too tight or else you might crack the part depending on how it was printed. A dab of superglue on each side and this hanger is all ready.

If you would rather try to screw your bottles in, I would scale it up a few percent (3-5). Don't scale too much though or you won't anything to grab the inner surface. Of course, unless you would rather just push the bottle top right into the socket.

Love the idea, this would definitely be easier on jacket shoulders than a metal hanger, and use less plastic than the wide suit hangers (reusing the bulk of the material as PVC)

Downside is the amount of room this would take up... My closet space is limited as it is, I can only imagine how little space I'd have after I hung a dozen blazers on these.

you said you used makerbot to print this!?

Sure did with an MK6! I have made some tweaks to my skeinforge preferences, but no extensive hardware upgrades.

On second thought it seems like steel wire coat-hangers are probably more environmentally friendly -- most metals rust away faster than anything else can decompose, and its not clear that ABS used in 3D printing is really environmentally friendly, especially since we don't have good ways of recycling prints yet. PLA is 'Biodegradable' but will only degrade faster than normal plastic under special conditions, if I understand correctly. There are many problems to solve before 3D printing can be considered sustainable.

Wire hangers are really hard on the shoulders of blazers and suit jackets. This allows for a nice rounded shoulder while using a minimum of "new" plastic and reusing existing plastic for the bulk of the size. Plus, you don't have to jump in the car and waste gas to go to the store to buy a pack of jacket hangers.

Using these for everything in your closet would be crazy. I bet I can fit a dozen dress shirts on wire hangers in the space of one of these hangers.

You can use an extruder to respool your waste. Look up the filastruder you'll be happy I told you about it. I don't own a 3D printer quite yet but I'm getting one and an extruder to recycle my waste, and cut down on cost.

I would agree with you on the decomposition front - if there was a way to recycle the prints and/or use a material that biodegraded faster, that would be more friendly from a waste management perspective. It also would be more environmentally friendly from an energy-usage perspective if this wasn't a one off and was injection molded too. This design was intended more to highlight the ability to recycle the bottles that could have ended up in a landfill into something useful.

You may have seen this, but this type of 3D printer is much more in a sustainable direction:

What a brilliant idea!!

This idea is amazingly clever! What a wonderful way to combine a 3D printer and recycling bottles to make a useful product. :)

Awesome! Its kind of funny looking, but its definitely a way to recycle 2 bottles for something useful!
