Description
Most soap in the world is provided in the form of bars. Bars, that are deployed on grids or basins, that inevitably turn into a rather filthy, slimy affair.
This soap bar dispenser works differently. The soap bar is never in contact with water. Using the sled, you shave off flakes of soap from the bar.
(Note - the dispenser in my picture was aborted in mid-print, because I ran out of ABS and changing the spool did not work as expected. The model dispenser is higher, and the scad file is parametric anyway.)
This thing is public domain, because caring is sharing and I am counting on the thingiverse hivemind to make this more awesome. Feel free to flattr me or any derivatives if this is useful for you.

Instructions
The scad files are provided and mostly parametric. If your soap bar does not adhere to international standards, feel free to adapt. It also adapts to different blade sizes, and even finger sizes.
Print one copy of the dispenser and the sled. Clean. Insert up to four blades into the slots. Razor blades do work, but something more stable is certainly a plus. To insert the blades, clean the slots in the side walls with a scalpel, to make sure there are no obstructions (and those in the center if they are not perfectly flat). Insert blade in one side, carefully snap the other end into the other side with a bit of force and maybe a pair of tweezers. Don't hurt yourself.
Attach the sled to the dispenser, insert soap bar.
Moving the sled forth and back will provide you with soap flakes. You can use these to wash hands (I presume).
Both parts are printable without support and raft if your settings are good. The sled prints without support either lying flat (one or two filaments will drop from the overhang) or upright on one of the two sides (results in a much better grid, but is high and narrow and more difficult to print).
This is marked work in progress, because there is a lot of room for improvement. Please do so if you have any ideas. I am thinking of:
- A wall mount
- A better way to attach the blades. They should not be able to slip out under pressure. (They don't but I don't have a good feeling) I am thinking of a two-part snap-together system, but it is difficult to realize with these fine structures and rough printers. Maybe a combination with thingiverse.com/thing:3090
- One hand operation with a spring.
- Maybe add a bowl to put the whole contraption in, and to catch any residue soap flakes.

Nicely done -
This could totally be wall mounted, and with a spring-loaded shaver, push in and shavings fall down.. I like the short sleeve with the soap sticking up.
Though in some ways this feels like a solution to something I never knew was a problem.

Thanks :)
While this very short sleeve is my print failure (albeit aesthetically pleasing), I designed the model not to cover the whole soap. But it should provide enough grip that you can hold it with wet or dirty hands, or you are stuck with the same problem as before.
I also didn't have a spring mechani
sm at hand, but like I said, I am counting on the hivemind to improve on that. :)

I love the design, and it makes me happy that less than 2 weeks after the original idea hit the internet, there is a printable version, but attribution, attribution, attribution!
Always credit the author. (Note: if you're actually Nathalie
Stämpfli, I apologize)

this design is much safer than nathalies.
her wall mounted design would be quite dangerous for your fingers.
Never doubt the online community. If an idea is put on the internet, it would be made or reenacted.
hoeken,
While I agree that Nathalie might have done a new twist on soap-shavers... We had the exact same thing in the bathrooms at school in Denmark some 25+ years ago. don't really think there is new "invention" here at all.
Ah! I apologize. I did not know the link - I have picked up the idea in a discussion, but I don't doubt it was sparked with that thing in mind, seeing how the Internet operates.
