Keychain gripper with rubber and capacitive touch functionality

A keychain gripper/door opener with added rubber for enhanced friction and aluminum inlay to operate capacitive touchscreens (smartphones, atm's).

This tool is designed as part of the #NoTouchChallenge and it addresses two weaknesses of previous designs:

* The plastic in itself does not provide enough friction, so grasping things is challenging. Some designs have addressed this by adding rubber bands. I think a rectangle piece of rubber glued into the design provides a more solid solution.
* Touchscreen displays are a common interface that might be a source of virus/bacteria spread. This gripper uses an inlay of aluminum foil to allow for operating touchscreens with the tip of the gripper.

__Additional materials needed:__
* Rubber piece (205x5.8x2), a stencil is attached: rubberruler.stl
* Aluminum foil (multiple folds resulting to 130x5)
* Superglue

__Assembly:__
* Glue the folded aluminum foil in the slot so that it reaches from the top of the handle to the tip of t
