This is the first generation top cover riser for HPPS. (High Performance Panel System; Proprietary foamed-silicone panels for X1/C/E & P1S)
Use this if you would like to print lower lower-temperature materials (such as PLA) utilizing an HPPS-enabled machine.
ASA or PETG is the recommended material for these parts due to UV-tolerance & thermal-resistance.
