hey guys, this model can either be printed as one or two, and this model is something that you print and when you print two of them, you put one at each corner of the printer, and slot in cardboard to make it a wall,, if you print 4 of the double then your m3d micro will be fully enclosed,,, and as it is cardboard rather than plastic then there will be less noise as plastic amplifies it,, this will help with warping, almost stop all warping with pla and assist wil abs, and it also covers the motors so less sound if it is in your room, just print as is, with raft on, if you want then wavebonding, (better safe than sorry) quality and fill does not matter, I iused medium and low quality, and low fill, it takes between 1 and a half hours to 2 hours.
