Those lines on the bottom i find quite weird, tho then again i am a rookie to this. Almost looks like some of the initial print lines are getting ripped out. but i guess you would seen that happening and included that in previous posts. No clue what it could be. just to be on the safe side, check the first layer on your slicer program, look at first layer if it has any gaps in it's printing plan. i doubt that is the case tho
