I bought a Poly Pit Butler when they first came out 30 years ago for £19.

   

It served well as a storage box for small parts during the years I raced RC cars.

In 2015 I joined the local Slot car club and the PPB was perfect and I've used it since.

There's currently 19 cars in there.  The bottom tray is full of tools.  I carry race-night bits & bobs in the box.

   

I acquired a Dewalt bag which is used for the three controllers I use (Synapse, Third Eye Gawronski, SlotIt SCP1).  There's also a GoPro, charging block and leads and whatever else will fit if needs be for race night.

   
   

Then there's a box for Slot Rally, an old sewing box the missus was chucking out, now filled with Rally cars (probably 20 or so) all in separate plastic bags.  Also room for a handful of timing sheets for club members.
