AAA & AA storage block

Had a load of AA & AAA cells rolling about so made this on Freecad 0.21.2.
I normally work in Inventor but thought I'd persevere with Freecad which is ok for simple stuff like this.
Made to fit in some plastic boxes I have 62 X 97X 27 mm high without cells, 53 with cells.
Added the cross holes to help keep the base flat, first attempt curled off the bed mid print.
