Been fed up chasing tools around the desk or from a tray/drawer, so created a tool rack as shown, which screws to the underside of the shelf that runs over my desk in the Summerhouse. The rack has a variety of cut outs to take as shown all the tools I like to have to hand when dabbling with slot cars.

   

Rack prints upside down without supports and is 264 x 61mm square so should fit most FDM printers.

And a short version in 2 parts for those with tiny printers.

That's too large for an Ender 3, as well as a Prusa Mk3. Prusa can fit a flat thing up to 250. An Ender 3 is limited to 225mm.
