Threaded remix of fan-out card wallet

I liked LoboCNC's fan out wallet so much, but I'm clumsy and tend to drop it. When I do, the plug sometimes rockets out, leaving my sleeves all over the floor in a mess. I finally broke the first one I printed back when they released the model (left it in my pants in the washer, told you I'm clumsy…) so I decided to add some threads. I've included the original sleeve and FanCaseBack models, only the FanCaseCover has changed so you can also swap it out in your current wallet. m3x12 screw + m3 washer, shorter will also work I'm sure I used default 0.2mm quality profile in prusaslicer print 5 sleeves
