I made this tray for some of the tools I use regularly.
Option 1: If you have a printer that is capable of printing parts that are 320 mm wide you ...only have to print the Complete.stl
You will also need 4 Self-adhesive felt pads, about 3 mm thick
It needs to be printed with supports. Please bear in mind that I couldn't test print that thing so I'm not absolutely sure if it will work properly. A "Make" would be nice
Option 2: If you don't have suche a big printer, you can print all the other files and will need some additional parts:
1 piece of plywood 288 x 140 x 6 mm
4 Screws M3 x 10 mm
4 Nuts M3
4 Self-adhesive felt pads, about 3 mm thick
The bit holders fit 6,3 mm and 4 mm bits.
Slider.stl, Rail.01.stl and Rail.02.stl are needed to be printed 2 times
