While trying to print the "Flap", I noticed that the first layer was printing a bit off. Only printing half of it then on the second layer it would print the other half. So to fix this all I did in Slic3r was rotate .25 deg on the X axis. Now it is printing fine. I also hear others can't get the flap to fit or they break it. So I figure it has a weak spot. I upped the infill to 30% and 4 shells. I am printing with silver PLA, 0.2 layer height, 0.4mm nozzle. Printed everything else with 15% infill, 3 shells and NO supports what-so-ever!
If I end up breaking this part I will just have to print it in PETG.
Thank you so much for the awesome machine! Loving it!
