This is the 4th sliding spice rack in a series. After seeing the size of the 100mm version and the 150mm version next to each other decided to make this 125mm version. For this version, the basket is 125mm wide. You will need a large printer to be able to print this. The total length is 280mm.

The top rail has to be put onto the base part before installing it in the cabinet. Slide the rail all the way forward and put in the screws. I used #6 wood screws 1/2 inch long. The basket is glued onto the top rail. I use an acrylic glue (SCIGRIP 16) that IMHO is better than super glue for PLA. It has some nasty chemicals in it though. It just requires careful application and good ventilation. Gloves are also recommended. Super glue works too!
Print with 3 walls and 10% to 35% infill. No support needed. Also recommend using a brim.
