These are the STL files to print a small box to organize nozzles and basic tools used with Ultimaker 3D printer.
The small cilinders must be glued to the back of the nozzle holders to give them space.
I used Fast Print with the 0.4 mm nozzle, and PLA, with supports for the tools holder (herramientas) only. No supports for the other pieces. It took me a little more than 2 hours to print.
