The wrench- and hexkeyholders and the pliers holder are just remodels of Drovious's model, a holder for the brass brush, the Nextruder Nozzle boxes, a holder for the lubeTube and all 3D-Printed tools from the CORE ONE kit have been added. I have also added a holder for the nozzle changing tool (the version for no silicone sock!).

The lids from Drovious's original upload can't be used for this model, as it is bigger!

Gridfinity base:
The model itself is already prone to warping because of its size, but with even less surface contact this problem will get even worse. I have made the first layers of the tray above the gridfinity feet a bit thinner, as there is also stability provided by the gridfinity framework, to help a bit to combat this.

Updates:
2026-01-06: Added normal tool tray
2026-01-11: Added gridfinity base version
2026-01-12: Increased thickness between gridfinity feet top and tray bottom

I'm not affilliated with Prusa Research in any ways.
