I have a West Elm Drawer/Console and the drawers don't stay closed. They just pop back open when I closed them and I narrowed down the problem to these black rubber stoppers that go on the back of the rails. They bend and break and fall off pretty easy so I said no more and I designed these stoppers to fix all of my problems. I printed these with SUNLU 95A TPU but you can probably get away with printing these in PLA. Hope this helps somebody. If you have any questions please just post a comment.
