Toolown is a multi-use tool that you can customize, assembling the modules that you need.
Each module has different functions:
you can find a spoon, a fork, a knife, but also stand for phone, a bottle opener, a post-it holder...
According with your needs, you can easy assemble your "swiss army knife",
thanks to the bolt that keeps together the modules.
This is an open source project: you can find it on Thingiverse,
you can dowload the modules that you want, and print them with a 3D printer.
If you search other functions, you can create the module that answer to your needs.
On thingiverse you can find the default module, with the measures and the constrains.
In this way the project is the coherent also when different people contribute.
Here you can see some trials of 3D printing.
