Auto Retractable USB Cable Management

We do have a place to charge our devices in the living room.
But it was always a bit messy when the cables where laying around unorganized.
We tried to use a simple solution, but most of the time one forgott to put the use cable back.

So I came up with a solution to automatically pull back the cable after they where used.

It consists of 3D printed parts:
1. A pipe to be filled up with sand acting as a weight
2. A funnel to guide and stop the charging cable into the pipe
3. Weights to pull the cable into the pipe

And some stuff from the hardware store:
1. Isolation pipe EN25 (~5x 50cm)
2. M2 Screws and Nuts to assemble the weights
3. Threaded insets the the pipe clamp
4. Screws to mount the pipe clamp
5. Superglue to glue the lid the the weight pipe
