OK, the insert I made for my Multimaster starts out just as a 6mm MDF base, shaped to fit a Systainer, and with 12mm MDF partitions glued in:-
These take the Festool coloured boxes that house the blades and accessories...
And the whole thing just drops into a Sys 1 with the Multimaster...
There isn't that much space for the MM to rattle around in there, but if you were worried about it it's easy enough to add some padding for protection.
Edit: OK I give up trying to get the images inline with the text - life's too short and you get the idea, right?
