Bit holder box for ELECTRIC PRECISION SCREWDRIVER XIAOMI WOWSTICK 1F +

I bought the fantastic XIAOMI WOWSTICK 1F + lithium electric precision screwdriver and, as more and more often happens with Chinese hi-tech products, I admired the fantastic packaging and the completeness of the accessories, including a very beautiful portable case for the electric screwdriver.

But it can only contain one of the three sets of bits provided, contained in three transparent tubes rather inconvenient to use when working and needing fast a particular bit. So I had the idea of ​​modeling a bench bit holder that could always make available the 56 supplied bits  and, possibly, have some extra space free.
I propose two versions of the bit holder, in which I also added an extension for accessories. You can decide to print the bit holder with or without the extension.

Note for 3D printing: I recommend that you print to 100% scale, with a slow and fine slicing profile (0.12 mm); in this case, I reccomend to set filling no more than 8-10% to get the result in acceptable printing times.
