Nice design. I'll likely remix it with deeper walls, as I prefer to put the LED strings along the outer wall, and cover the back with aluminum tape, as I don't care for the light stripes you get from mounting the LED's to the back.
Have to agree, If I had it to do again I would have run the light strip around the wall. That is where the diffuser came in, I had already glued the LED strip down and was getting striping. :(
I'm not sure it needs to be deeper though. There is enough room to run two LED strips around the wall. What ever you decide though let me know how turns out.
I have an A1 Combo. It will Slice but will not send to the printer due to incompatible parameters. I am too new to fix. I have red/white/black loaded but the files load 4 more filaments totalling 8. I am confused.
It is loading eight because the profile is showing my device set up. I am running two AMS (8 colors). That shouldn't cause an error. When you send it to print and the window opens, you just click on each color and match it to the colors you are running. If you can't figure it out, let me know. I can update the profile with only 4 colors loaded
