Window track for RV/Bus sliding windows

Eventually sunlight and use breaks down the originals, probably these some day as well. These fit my horizontal sliding window. They are common on RV's and some buses. I used PETG. Was able to extract the originals and slide these in place without removing the windows. 2 years later still working well. The weep holes are important, and make sure the weep holes in the metal frame are clear of debris. FreeCad files included. At the time I used a Prusa Mini+ so they are a little short, you may need two or more per window.
