Filament Holder 8 Rolls IKEA Kallax

This model allows eight 1kg filament spools (200mm diameter) to be stored in one cube of an IKEA Kallax. Great for space efficiency, and I find it straightforward to get the rear rolls out. However, this might not suit everyone as you have to remove a front roll to access the rear rolls. 

Extra parts required:

1. 1m x 19mm OD tube/rod per cube (20mm will fit but it will be very tight).
2. 6 x 8g 16mm Button Head screws per cube.

Installation is straight forward: the parts are dimensioned so they sit flush with the front/back of the shelf. Simply line them up and screw in place. Then cut the 1m tube into three equal lengths 330mm and drop into the support slots.

Expected Kallax dimensions: 335mm(W) x 335mm(H) x 390mm(D).

Print settings: 4 walls, 20% infill.

Orientation is wrong, sorry. Use your slicer to reorient the pieces.

Notes on different versions:

• V4: My preferred option, simple to print and holds over 40kg.
• V3: Slightly narrower front supports with higher screw hole.
• V2: A design for screwing through the base. Originally this was so the storage can be free standing rather than attached to walls. Has chamfers on the tube insert to put some form stopper (not supplied) on the tube. Requires extra screws.
