From the designer:
This is a custom insert that I have designed to fit your Milwaukee Packout to store your M12 Dremel/Rotary Tool and accompanying your bits and kit. It specifically fits the Milwaukee 48228435 PACKOUT Compact Organiser.
The specific M12 Dremel/Rotary Tool that this is designed for is model C12RT-0, link is provide here: https://www.milwaukeetool.com.au/power-tools/speciality-tools/rotary-tools/C12RT-0.html
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. I’m also working on developing a design for the actual Dremel branded rotary tool for any that are running that instead.
