The original make would not fit in the box I got at Target, Ezy Storage 19qt IP67 Waterproof Storage Box. So it was remix time.
Print 2 A-braces and spools. Only 1kg or smaller spools.

4mm button head screws hold the pieces together and I used an 8mm carbon arrow shaft to mount the spools.

The 4mm screws will split the cross braces due to the lack of layer adhesion. Using a 4mm tap will help

The original design is really nice but I could not fit it in the box I have. this one will only work with 1kg or smaller reels. It also took a lot of time and filament to print. This design may not survive Armageddon:)
