I spent my last penny, so I needed to (p)improvise this thing :)
No seriously, the penny is the most expensive part of this bottle opener, so I decided to reduce its cost drastically.
Well, actually, I simply didn't have any US coins at my disposal and even a penny makes for a pretty bulky bottle-opener, so I decided to use what every Mendel hacker has at least a few kilograms of: M8 washers I shaved of a few flats for this design to be printable in 9 minutes on my Ultimaker at 100 mm/s (0.3 solidity). With PLA this makes for a pretty strong bottle opener.
The .SCAD file just imports the original file by Nick Starno, and takes a few slices off it where it's not essential. I will do extensive testing with beer bottles :)
Thanks Nick, for the "original derivative"!
See the video of it being made and used, in 9 minutes!
9 minutes is the fastest I could print it without too much compromise in quality, it could be nicer if you have a little more patience. The opener does look better when you print it at around 70mm/s, and it'll take about 15 minutes.
penny_opener_mod.stl is the result, penny_opener_cut_1.stl is the source file that is adjusted through OpenSCAD.
- Put beer in fridge, or the freezer if you print it fast... ;)
- Start printing
- "Insert coin"... no wait. Insert washer!
- Open bottle
