The last days i saw the PTFE scrubbing on the metal of the Printer-Frame under the Top-Glas on the right Side.
I saw some scratches on my PTFE also .So i desinged a quick and easy solution.
With this simple Thing it can nt scrap on the metal anymore.
I designed a Hole on it for the middle screw of the Frame.
2 places ar a little bit lower, for the double Sided Tape (delivered with printer).
I printed in PLA for the beginning , look like its not necessary to print with other filament.
I used it already for printing ASA with 42 Deegre Celcius insind without problems.
