I've been using @mkuiper's stacable cable clips for some time at home and on the go but still it was sometimes difficult to find cables and charger in backpack, so I've created a little stickable addition to charger.

Model got slots for vhb tape to be almost flush with the model, tape used is m3 5mm widh VHB tape which works perfectly for that application.

Depending on how you printed slot might be a bit tight, but should be just fine after few uses.

I've printed mine in Prusament PLA on Prusa MINI with default settings.
