Holder for Tools for Ultimaker 2+, Werkzeughalter für den Ultimaker 2+

I designed a tool holder for the Ultimaker 2+.
There are some out there, but this one fits my needs. Perhaps it helps you, too.
There are four holes for nozzles, a pocket for a razor blade and Slots for 3 Tools. The width of the slots is 20, 10 and 12 mm.

Support is needed.
Use a permanent marker to color the raised surface of the printed numbers. In the picture I colored them black.
