Gridfinity 1x1 AAAA Holder

1x1 AAAA Holder for the #Gridfinity System. Couldn´t find a 1x1 version, so if you, like me, made the questionable life decision of buying a touch pen without a integrated Battery, you now have a place to store your quadruple first letter of the Alphabet single/multiple use electron exchanging contraptions.

P.s. Sorry for the Puns, but I wrote them down on some A4 and now they are tear-able...
