Braun Series 7 Shaver Power Cord Holder

Braun Series 7 Shaver Power Cord Holder, circa 2010 model
I usually disconnect the shaver from the wall outlet after its finished cleaning because of an annoying high frequency noise it makes. To prevent the plug/cord from just dangling off the base, I designed this small holder for the plug. It simply hangs off the side of the Braun base and keeps the plug in a tidy, easy accesible location. It works on either side of the base.
There are two sizes, long and short. The short one is 1 cm shorter than the long one, but otherwise, the holder is identical. I have the longer holder attached to my base on the side of my sink, so the cable hangs vertically down. I made the shorter one thinking that the cable would touch the surface if I moved it inwards, but it turns out that it doesn't and it doesn't push the plug upwards.
