.STL File / 3D model: MIGHTY BOTTLE OPENER

UPDATE: I've been not able to discover a reliable method to protect the plastic with this layout. If you're using PLA, continue reading; folks have had good results. If you're printing with ABS however, I recommend using this updated design: http://www.thingiverse.com/thing:11025

The Coin-Op Bottle Opener (http://www.thingiverse.com/thing:1842) is awesome on so many levels. No wonder it's often published on a device. It doesn't take long to see its weakness though.

This design keeps the same (strong, satisfying) jaw geometry, but puts it in a package that isn't a burden on your pants pocket. Also, because it's much smaller, it takes time to print.

One drawback is that you need to man-handle a paper clip to keep the plastic from getting chewed up. On the plus side you get to call yourself "crafty."

I also removed all the handle, so you might need to adjust your hand position that was normal. I find this opener works best with my thumb on top, index finger underneath.

(I have left this as a "work in progress" for the time being. It's done well in my testing, but please let me know if something doesn't work for you)

History:

  • Part gets submitted using a modified jar cap as the protector. Looks awesome (it's still the name thumbnail)
  • Item gets featured.
  • Turns out the bottle cap protector doesn't work all that well. Embarrassing update posted. (good thing it's a "work in progress")
  • Furious design session yeilds improved paper clip design. (thanks go out to thingiverse users waaronw and jprodgers for their contributions to that process)
  • Made the component ~1mm wider (to help the fill around the hole) and added a little recess for the paperclip on the back side.

Directions

Finding the Paper clip into the opener is pretty straight forward (see picture):

  1. Straighten the paperclip and bend it into a U.
  2. Slide the clip through the slots at the part until the U is flush with the back of the opener.
  3. Bend the free ends so that they are flush with the front of the jaw.
  4. Trim the ends so there is just enough cable left for the next step.
  5. Bend back the wires forming two new U's. The points must be lodged into the plastic at the back of the jaw. This will keep everything comfortable and nice.
