Gridfinity storage and magnetized lid / base

Hi all,

For a soltering tool kit, I'm using a ReallyUsefulBox 3l. 

Trying to maximise space and having already printed the TS101 storage box, an existing box was modified to give an internal storage space height of 50mm. 

The magnetic base was then REMIX'd to create a lid, the the existing Gridifinty cases can be placed on top (see image)

The images show the printed files in PETG, with a 0.6 nozzle with a layer height of 0.4.

Not added magnets yet but going to use 6x2mm for the base. Not tried 6x3 in there.
