Simplify3D User Forum

Hi there!

I am trying to print this part of a box (for some MTG cards), and it is supposed to be completely hollow in the middle so that the cards can fit in. However, S3D seems to be creating a single bridging layer throughout the entire middle, and for the life of me I cannot figure out how to get it turned off. I have scoured the forums looking for this same problem and have been unsuccessful in finding a solution thus far, so I thought I would create my own post about it. I have messed with my bridging settings and "Unsupported Area Threshold" settings, but nothing seems to work. When I set the Unsupported Area Threshold to its maximum (99999mm), instead of creating a single bridging layer, it creates a single solid layer. Is this a problem with the .stl file? No one in the Thingiverse comments for this piece seem to be having this problem, so I am stumped! Any help would be most appreciated. Thanks so much in advance!!

P.S. I am attaching a zipped file with the .stl file and my fff profile. Thanks again!!

This is another corrupt Thingiverse file!!

You need to repair the file.

If you have Windows10, use the 3dBuilder app. Simply load, and it will want to repair it. Once repaired, Save as an 3mf file and load into S3D.

Alternatively, use one of the online repair services...
