“I thought the Pocket Coin-op would look nicer with some tapered edges. the rounding also makes the opener lighter and speeds up the print a little. 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!”
