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.

  1. Put beer in fridge, or the freezer if you print it fast... ;)
  2. Start printing
  3. "Insert coin"... no wait. Insert washer!
  4. Open bottle
  5. Cheers!

how'd you get the real time control and tuning?

Very nice BTW

Erik - in reply to sockles

@sockles: Real time control is one of the parts that I programmed into ReplicatorG. It only works with 5D device drivers such as Ultimaker or RepRap. It probably works best when you download ReplicatorG from http://software.ultimaker.comsoftware.ultimaker.com.

I want one! (the printer, of course if I wanted the opener i could just make it right now)

wow that is very impressive. when can i buy that printer?
