ender 3 lower guide for BMG or BMG clone extruder

thingiverse

This is a remix from robathome and holspeeds guide, they both did a great job on this. The design I remixed this from was here http://www.thingiverse.com/thing:3061551 I have redsigned the main bracket so that it can be used for a BMG or BMG clone extruder, I have had to make it wider and taller to allow for the different position the filament goes into the extruder. The wheel and the spacers are the same. If the model isnt already, then lay it on its back in your slicer so no supports needed. edit* changed the bracket STL so it should be laying flat ready to go. print settings. layer height, 0.2 infill, 30% nozzel, 205 bed, 60 print speed, 50mm/s no support material, PLA. the wheel should be printed with lower layer height, use 0.15mm and 100% infill. the spacers are stronger printed at 0.15mm layer height, 10 degrees C hotter than usual with 40 mm/s speed and fans on full after 3 layers. extra parts needed. 1 m4x20 round top bolt 1 m4 nut standard 608 bearing (very common in spinner toys).
