LED strip holder made for IKEA Kallax. Allows illuminating all compartments in one row with a single LED strip. 

Easy to print and install (just 2 self tapping screws or a double sided tape). 

End caps and wire channels included. There are 2 versions of the light bar, one piece and split into 2 parts (depending on the size of your printer).  Also 2 versions of the wire channels, 10mm and 14mm size (for thicker wires). If you can't print the channel as one piece, just scale it in the slicer along the longest axis.

Slicer placement example: 

Single rail (for illuminating one cube) uses 31g of filament with 100% infill.
