Kallax Rack Modul 5x5 – PRED Gridfinity Toolcases

This 3D printable Kallax Rack Module was designed to neatly and space-efficiently organize Pred's Gridfinity Toolcases (6U 5x5) in the IKEA Kallax shelving unit Click here for the 5x4 version
The boxes can be easily inserted and removed without additional guides or hardware

On the left and right sides are additional small parts compartments, ideal for screws, nuts, bits, or other small items
Each side compartment can be flexibly subdivided with up to 8 plug-in dividers, allowing the compartments to be adapted to individual needs, with the last 3 compartments being larger than the rest

Note:
For the side pull knobs (to easily pull out the compartments), 10 M3x8 screws are needed (1 screw per knob) As an additional variation, I have also uploaded filament spool door knobs as a separate project
The dividers and knobs are optional, the system can also be used without them

Version 1 – Glue Assembly:
The rack is printed in several parts and then flush glued
A version with interlocking guides is planned

Note on Print Time and Material Requirements:

• This rack is a larger module and therefore requires significant print time and material
