I replied on thingiverse to your comment. I don¡¯t know if a 20x4 would fit I will take a look when I get home. I have one on the shelf I got from sparkfun.
The mounting holes can be different from screen to screen as well. Also your slicer software should be able to lay the top flat on the print bed.
2) can you rotate the top so that it prints face down??
?
I cannot quite get it to lie flat with Cura. I can rotate the top so that it stands on it's rear end. This cuts 2 hours off the print time and rotating it onto
ifs face cuts that down even further to just under 4.5 hours. But I still can't quite get it to lay flat on its face.
