The basic idea is that there is a hand with holes in it, which holds a soap. So the water of the wet soap can run off and does not dissolve the soap.
This model is a remix of Teak's Hand which was passed through this cool Voronoi online generator here: http://www.voronator.com/.

Update 2024-10-11: added a version where the hand stands on a base for easier printing.

Update 2017-11-01: added a simpler mesh with reduced polygon count that prints out fine.

Notes: 

I printed it in black PETG with a raft and without support.
Overall it printed out very well and is surprisingly sturdy.

I still have stringing and blobbing problems with my printer and that PETG, but that is not specific to this print.
