Shelf for IKEA BILLY / OXBERG with notch for hinge

To store my filament spools, I use the IKEA BILLY / OXBERG cabinet and wanted to make use of the space between the two fixed shelves in the middle section.

This shelf unit is specifically designed to fill the open space in the IKEA BILLY / OXBERG cabinet next to the hinge on the right side. Unfortunately, the vertical clearance between these two fixed shelves is too small to accommodate filament spools.
 

To utilize the available space, I designed a compact shelf with drawers that fits between the shelves and encloses the hinge on the right side.

The handles are fastened using M3×8 screws and M3×5 press-in nuts.

Grid insert trays for tools and 3D-printing accessories for these drawers are planned and will be added soon. 

Feedback and suggestions for improvements are welcome.
 

Feel free to make improvements and share them with others.
