Gridfinity 1x1x6 vase mode box only 6g

Inspired by other gridfinity boxes I've made mine 1x1 box that can be printed with only 6g of filament 
My print settings are: vase mode, 3 bottom layers, .28 first layer height, .2 other layers height, 0.6mm wall thickness

I was printing them with PETG

Yes I know this is not the box that can handle a lot but hey we are printing from air here :)
