You may need to adjust your flow rate I have mine sent to 1.08 just depends on your printer and make sure you have arachne turned on for wall generator that way you don't have any pin holes showing throw the front of your sign.
I changed color a touch. instead of blue I did brown. color comes through great. only issue for me... the stand doesn't have a notch built in to allow the wiring to come out for the lighting. as the hole is blocked by the stand. I need to throw the mesh into fusion and fix this and reprint a stand but over all it works and looks great. used designers print settings
