You may need to adjust your flow rate I have mine sent to 1.10 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 added a negative part to the frame and have it sized to10mm for the light strips I use but you can resize it to whatever size you need and move it to anywhere you would like for the wires to come out at that way it's completely customizable for the person printing it.

I added a 2nd back cover and have it colored to match the front plate, but it takes a lot longer to print.
