From the designer:

This is a custom insert that I have designed to fit your Milwaukee Packout to store your Cordless Dremel 8200 and accompanying your bits and kit. It specifically fits the Milwaukee 48228435 PACKOUT Compact Organiser.

The specific Dremel Tool that this is designed for is model 8220, link is provide here: https://www.dremel.com/au/en/p/dremel-8220-f0138220aj

With this insert you can maximise every single part of the Packout! The tool insert lifts out to reveal even more storage underneath for supplies! Plus there's the large tubs so you can add even more of your supplies and batteries into. The organiser tub on the left is also double layered, allowing for even more bit storage underneath. Furthermore, the design interlocks into the underside of the lid to keep your kit in their correct tubs.

We are now offering latches with tool names on them to easily identify which cases have which tools in them.  Latches are sold in pairs and can be purchased with the matching insert for a discounted price.  Picture shows other latches, but pictures for the latches specific to this insert will be forthcoming shortly!
