Drawer Bottom Edge Runner

I printed in:PETG with 4 walls, 25% gyroid infill Under the STL/CAD file drop down is the Fusion 360 exported F3d file if you wish to alter dimensions easier. This drawer guide was designed to restore smooth function to old kitchen drawers that the roller guides had chewed the bottom edges to saw dust. The Cabinets aren't pretty, but they are very sturdy compared to modern newer press board type construction. So I hate to replace them. Of course the back center roller and front center lose screw mounting points didn't help the drawer in any way allowing for even more wear on the edges. It was soo bad that in part of the drawer it had worn a section almost to the drawer bottom insert. I can not tell you how many times my wife complained about the sawdust getting inside the pots and pans. Then the new 3D Printer comes to the rescue and about 200g to fix 3 drawers for less then $5 sure beats the alternative. Measurements are as follows. 228mm long for 9" each. Two fit perfectl
