This is a simple organizer I created as one of my first models after I got 3D printer.  It may be used to place near your printer to have most used tools quickly available when you need. 

I added placeholders for four magnets to be glued inside and used for iron tools or other printed tools with a magnet inside (e.g., scraper). I used white color for body and grey top, but it is up to your taste of course.

3D logo may be glued to make it better looking (I used blue filament for it).

The top is to be screwed using 4 standard self tapping M3x5 screws available everywhere. 

Nothing special is required for printing - standard settings are fine as well as any filament.
