I've got a Monoprice Maker Select Plus that I've done a bit of modding on. I used a few different filament brands, but best result from ZYLTech PLA. The trick for me was to use 2 walls, 10% infill, and 5 top/bottom layers. Typically, threads a a b***h to deal with, but these worked friggin' perfect. If all else fails, SLOOOOOOW down your printer. Best of luck!
