This is a very simple but usefull tool box.You can have all your main tools aranged in one single space on top of your printer without any intromission with your working area.It is designed to be attached to the top rail of your printer. You just have to unscrew the two bolts of the upper rail and gently slize the two bases.It has two round holes on the bottom to attach a couple of 6mm x 1mm round magnets. But you can attach it with hot glue or similar.I also added 6 holes on the front to attach 6mm x 1mm round magnets

It has been designed in sketchup and converted in several formats just in case you want to edit it.

I´m adding an stl format that was saved with the requirements to print on an Ender 3

I´m adding also a gcode format that is ready to print on an Ender 3 series.

The presets are in LOW QUALITY. I experienced a very good printing with this settings, but if you want a better finish I sugest you to print it in super quality or dinamic quality.There are no support nor plate adhesion.

Temperature was set for PLA at 195° on the nozzle and 50° on the printing bed. This settings are the best for my printer.
