What is this storage space for?

It's obviously a spot for resealable caps from your preferred beverages.

It's obviously a spot for resealable caps from your preferred beverages.

Or all the paper straws floating about these days...

I use the space to hold a few pens.

Spare pistol mags.

Full or empty?

If it's a roll, obviously empty.

I'll need to start an instagram account for all the colors you can get them in and what they look like in there... maybe I'll get some sponsors to pay for all my upgrades..

THIS. A roll lives full time in mine.

Now that is the first real use for the space. Can you provide any details on the base and how you attached it? I like that idea a lot.

It's a diamond base, and it's attached with either 2 bolts, or double sided tape.
