I remixed with only one hole and 30mm of lenght and adapted to my Table Saw TC-TS 254 of Einhell.
I used also another model https://www.printables.com/it/model/317480-featherboard-for-parkside-tablesaw/files for featherboard.
Now all is perfect for Table Saw.
Loaded you can find remixed Fusion360 file so you can use it to do extended slide.
