From the Designer, Jonah Pope:

This is a custom insert that I have designed to fit your Milwaukee Packout to store your Dremel 8260 Rotary Tool (Brushless) and all your accompanying and kit/Dremel Bits. It specifically fits the Milwaukee 48228435 PACKOUT Compact Organiser.

The specific Dremel models this design is compatible are these:

Dremel 8260: https://www.dremel.com/au/en/p/dremel-8260-f0138260na

Dremel 8250: https://www.dremel.com/us/en/p/8250-5-f0138250aa

Features - Super Flexible Design

Double Layered Storage - Two lift out trays reveal even more storage underneath the tool itself and the main bit storage area.

Battery Storage - Room to store your tool with a battery installed plus room for an extra in the included storage tub.

No Loose Dremel Bits - I designed my inserts to follow the contours of the Packout lid when closed. You can rest assured you won't have your Dremel bits jumping over dividers whilst in transport or carrying your Packout.

Quick Select - Dedicated storage slots included near the head of the tool for storing your most frequent bits for easy selection.

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.
