Drawer Guide Replacement

After 22 years, our drawer guides were all breaking apart leading to the floppy, wandering drawers. Our furniture came from ArtVan, I can't tell the brand, but looks very similar to a Broyhill guide someone in the forums was requesting. I threw this together in 3D builder. They are holding up well. Print with extra walls and generous infill for strength. I think I printed these with the tails sticking up and kind of remember digging some support material out of the holes. They may not be necessary if your bridging is tuned pretty well.
