Magic Keybord Marker

I have designed a Marking-Bar for my Magic-Keybord.I´m using the F1-F19 Keys for specific Funktions in Fusion360.Now i have marked ever Keys with the Funktion. The Bar is as wide as the Keybord,there is a Slot on the underside , so i can charge and use the Bar at the same.There is also a Slot for the On/Off Button on the right Side of the Bar. I use the BetterTouchTool (folivora.ai - Great Tools for your Mac!) for getting Funktions on the F1-F19 Keys.The Label is done with my Brother P700 24mm B
