I tried Buszmen's designs, but all of them were giving me to much drag on the filament and causing under extrusion. With how my print station is set up, I have had good luck with the stock TPU grommet and oversize tube. With that in mind, I used Buszmen's basic design and adjusted it so that could allow for the stock TPU grommet and attach via double sided tape. So far, seems to work well. I figure if it helped me it might help another.
