Tapered Pocket Coin-Op
by br3ttb, published
The thickness, coin-size, and taper are all adjustable in the scad. I didn't bother to test changing the other variables as I'm pretty happy with that geometry.
Bonus: Are you full of jealousy seeing all these dualstrusion parts popping up everywhere? well now you can stick it to the man with a three color bottle opener!

Maybe this is just a problem with the STL importer for Sketchup (I was trying to add my own logo to it) but what I ended up with (even before modification) was a model that was not at all manifold. So when I went to print it the MakerWare slicer kind of freaked out and just left out whole sections of the model. It may just be that most people are using SkeinForge and maybe that's better at handling these things, but can anyone confirm that the model is actually a proper solid?

For 3 color (you'll need a Thingomatic for this):
- Print taperedopener.stl. Make note of the number of layers
and the Z-Layer thickness.
- In ReplicatorG, open the motherboard settings form and write down the zoffset value.
- Now change the zoffset by the number of zlayers and layer
thickness (newZ = oldZ - nlayers*layerthickness)
- Print taperedopener-color2.stl in a different color. When skeining uncheck "Activate Outline".
- Print taperedopener-color3.stl in a third color. When skeining uncheck "Activate Outline".
- Open the motherboard settings and return the zoffset to its original value
- Remove your opener and show it off! ("Oh you've got 2 colors? How quaint.")
A note about Coin Insertion: It had not occurred to me that people might try to insert the coin by pausing mid-print. Apparently this works, but it's not what I do. After printing I slide the penny into the slot as far as I can. Then using a pair of pliers (one jaw on the penny, the other on the short edge of the opener,) I squeeze the penny in the rest of the way.
