Ive seen a bunch of risers on here but didnt like that they looked unfinished without going to the front edge. This model adds a nice OEM feel. 

This riser adds 18mm to the top glass height.

This riser design allows for an LED strip to be installed with or without diffusers for a softer light if desired.

With the P1S, you can use a USB LED strip with the USB port that is behind the the screen. inside the printer. 

I printed my riser in:

BAMBU PETG HF - Black

BAMBU PETG - TRANSLUCENT CLEAR
