@jefkin ohhhh.... Not much I can do about that, unfortunately. Both the input and output have the drive in the center, a 3x3 white cube around it, and a 5x5 red cube around the whole thing.

here's a screenshot :( https://gtm.steamproxy.vip/ugc/784113153111249569/CABDD1A16FB6F023943E573B7B71D5D68F07D5CB/

Hmm, I was getting very strange artifacts in the requirements and the delivery boxes, with cubes overwriting other cubes. I agree with @notgreat 's first opinion: it's impossible to tell what's needed. Looks like strange cuts in the outside red layer and white layer. Even though somethings are seethough, other's aren't and ... ugh, just ugly. Skipping this puzzle for now.

The problem was that there was an inner packing material different from the outer packing material. Since I couldn't see inside, I couldn't see the difference.

There we go! now you can see every block in the whole structure!

It does go into the center, but you have a point, I'll use transparent blocks

There is literally no way to know where the skip drive is supposed to go inside of the box. I assumed it was in the center, but that proved false, with an error on the inside that I couldn't see.

The actual mechanics of putting something into the inside were interesting but not particularly difficult.
