Kallax extra Shelf Holder

Add an extra shelf to your Kallax shelving unit.Without damaging the shelving unit!Only one 16mm board & 4pc 20mm wood screws required.I used PETG for better UV resistance.I created a loose fit (16.3 mm)and a tighter fit (16 mm).The tighter the fit, the straighter the board stands.Assembly:check fit:It is best to pre-drill now:Check Screw Size:Mount 1 piece first:done<figure c
