Just right click your mouse on the required version and select "Print Target" or save to your computer by selecting "Save Target As..." then print it out. Use something like Paint Shop to resize the image so that when completed the battery forms a cube with sides 7.7"x4.625"x1.25" (or 197mmx119mmx32mm).  Print onto paper first to check the size then print it onto the thickest card your printer can handle, cut around the whole shape, crease where necessary and glue all but the top flaps together. There is plenty of room inside for 10x9 volt PP3 batteries for the HT and a number of "C" cells wired in parallel for the LT which will fit neatly with the help of a bit of expanded polystyrene padding. If you solder the battery connections of the PP£'s together then take care as the connections only have point contacts inside and are easily damaged.

Be very careful when handling this battery pack as 90 volts can pack a powerful shock, as I found out. Also if 9 volt alkaline cells are used, due to their low internal resistance shorting the 90 volts together can deliver currents of several amps which can generate energies of several hundred watts and is therefore a potential fire hazard. You have been warned!!!!
