Other Issues:.08mm layer height is way overkill for this...I printed it at .2 and it's just as good, but it cuts about 7 hours off the print time. Also the model itself is not 100%. It's not a perfect letter D and has some weird geometry.
Worst parts about this file
1) no hole to route led power cable out of so I added a negative modifier in the slicer
2) the spot to hang it on the wall is horribly designed, with random tiny bits coming off of it
This is a good design but the print profile is not great. At 10 hours this is crazy it does not need that layer height. It does print but takes forever compared to any other lightboxes.
Edit: I actually need to take off some stars here because the back plate prints with the prime tower inside of it.... Had to cut that off and the edge looks terrible.
