Gridfinity 1x1x8 AAA battery holder

I found Xavierly's set of Gridfinity battery holders really cool, but i wanted to stack baseplates and other things larger than 1x1 on top of them, so i made the height of the AAA holder (was 7U) to match the height of the AA (8U). So i just increased its height by 1U (7mm). Printed it in PLA on standard settings (0.2mm, 15% infill).
