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)
- 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.
Finding the Paper clip into the opener is pretty straight forward (see picture):
- Straighten the paperclip and bend it into a U.
- Slide the clip through the slots at the part until the U is flush with the back of the opener.
- Bend the free ends so that they are flush with the front of the jaw.
- Trim the ends so there is just enough cable left for the next step.
- 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.
