Failed to Export file

Hello i’m trying to export a file that i remixed myself by adding a holster fixture of sorts for a lighter in the canister you see. For some reason im unable to export the finished design to any formati.e STL, 3MF, STEP or a Shaper3d file. I’m lucky enough to say that i’ve created several design successfully using Shapr3d so im honestly confused on where the issue is. I’ve read other discussions where there might be holes or other irregularities in the file/design itself BUT im unable to find any. Im fairly new to CAD so of course maybe i missed something? In any case could someone possibly take a look at my file and tell me whats wrong? Thank you

Hey. With view-only access, I can only see published designs, and you haven’t published them yet. To access the project, I need editor access.
