ScrewBox

These are different versions of a four arm screw-box.

I was inspired by the following design to make this one with the measures I need.

I have designed it mainly to contain an alto saxophone mouthpiece I printed (there are different models of it here in Thingiverse), but it can also contain any other kind of thing.

Edit: In the first version (1.1) was quite difficult to separate both parts so I've extended the base. I recommend to print the box
