Flight case for a 1/4 bass with removable neck

Maybe this is not the right place to post this but since its kind of related directly to the bass, I thought that maybe it's OK?

So, I(will soon) have a 1/4 bass with a detachable neck and I'm looking for a flight case. Of course, as small, light weight and as cheap as possible!
Any ideas?

I heard about some bicycle cases that might work but couldn't find the post right now...

 

It's a handmade wooden bass. I use it for jazz, tango, world music. Works for anything but classical orchestral music.
I'm tuning it from low G to high E. Soon I'll get a five stringed that I'll tune from low C to high E.
Here's my YouTube channel:

 

I really don't think that would work.
I heard it works for the eminence but this is a lot bigger!

 

Thanks!
I'm playing a lot of Turkish music with my trio. It's a minor(sometimes natural sometimes Dorian) scale with a 1/4 flat second step.

 

Thank you!
We'll make an album this year.
