ender 3 lower guide for BMG or BMG clone extruder

thingiverse

I've taken the design from robathome and holspeeds guide, both of whom did an excellent job on this. I remixed it from here: http://www.thingiverse.com/thing:3061551. To adapt the main bracket for a BMG or BMG clone extruder, I had to widen and heighten it, accommodating the different filament entry point into the extruder. The wheel and spacers remain unchanged. If necessary, lay the model on its back in your slicer to avoid support printing. Edit: I've updated the bracket STL so it now prints flat, ready for assembly. Print settings: Layer Height: 0.2mm Infill Percentage: 30% Nozzle Temperature: 205°C Bed Temperature: 60°C Print Speed: 50mm/s No Support Needed Material: PLA When printing the wheel, use a lower layer height of 0.15mm and 100% infill. To strengthen the spacers, print them at 0.15mm layer height, with an increased temperature of 10°C above normal and a speed of 40mm/s. Turn on your fans after three layers for optimal results. Required Additional Parts: 1 x M4x20 Round Top Bolt 1 x M4 Nut 1 x Standard 608 Bearing (Commonly used in spinner toys)
