About this 3D model
My office drawer did not come with rails to hold suspension files so I designed some rails that could hold the weight without bending inwards or tipping over. It's designed to fit into a 24cm wide draw but step files and f3d files are available so you can edit and adjust to suit your drawer. Orient the print as shown for maximum strength. I used PETG, 3 perimeters and 15% gyroid infill.
