HSW mount for p2s toolkit

I have a p2s toolkit (see link for details) and planned to print an HSW storage rack (see link for details), but couldn't find suitable and elegant connectors/inserts, so I temporarily modeled this item.

As shown in the figure, this set of inserts appears quite reasonable whether storing the p2s toolkit horizontally or vertically. For horizontal storage, simply install the two inserts with a gap of 2 horizontal grid spaces, and for vertical storage, a gap of 1 horizontal grid space is sufficient.
