Hi all, I'm a new M2 owner and wanted to post a couple of mod's I've made in case anyone finds them useful. The first is a case for an OctoPi Raspberry PI B+ that also acts as an LCD cradle found here: http://www.thingiverse.com/thing:1060104
The second is a new set of fan covers found here: http://www.thingiverse.com/thing:1060105
The fan covers have a small built in offset to eliminate the little washers. My printer was making a bit of a rattling sound coming from the fan covers on fast moves. It went away when I eliminated these washers and used all 4 screws to hold the fan cover down.
Thanks to everyone here who has posted excellent help and tips, and mods for this printer. Really helped get a newcomer going. These were printed in PETG, something my old printer couldn't even fathom. I love the M2.
