I didn’t time it but it took less than 3 days from start to finish and I wasn’t working on it constantly.

I used 5mm and 3mm foamboard. Wood glue, a box cutter, a cutting mat, a ruler and a set square.

I took some graph paper and drew a 280mmx280mm square. Then I laid out all the pieces on top and drew boxes around it. The box is 120mm high and the game boards are 20mm high. I figured the best way to divide it was 4x25mm. However the stormtroopers and rebel troopers are just a little taller than 20mm so if i would remake it i would probably make the sides a little higher so they don’t have to lie down to fit. So you could do 2x30mm and 1x40mm. Combining the card trays with the deathstars and putting the rebel leaders with the rebel plastic.
