Hmm I was unaware of that particular feature so I didn't make it like that. The inner box has the bottom screwed on, it doesn't insert. Then the outer lining is just screwed on tight to hold all together and mask the bottom. It all comes apart with Philips head dipped screws but could make it easier

Thanks for the candid response and that's about what I was thinking. I will note that the wood being cedar should help some with longevity..
