Mouse bungee

Mouse bungee a tried with my Logitech G502.

I have just tried to print one and test it with my mouse and it works so far.
The feet is placed under my mouse mat and it works.

In next version i will make it so the cable can be attached on the feet part.

UPDATE 2021-02-22
- Added a stiffer version of feather = Feather_v1.STL
