Earsaver for 0.8mm nozzle, 4 layers, 0.3mm layerhight

thingiverse

This is an upgraded version of makerjeff's solution for 0.8mm nozzles. I found that 0.4mm layer height was too much for my A8, so I scaled it down to 1.45mm overall height and added two rings to accommodate concentric pattern printing (faster and stronger) and glue the threads together at stress points. With a 0.3mm layer setting, this works out to four layers: two for the base strap and two for the ribs. Settings: 0.8mm nozzle Cheap PLA at 205°C, 55°C bed temperature NO FAN! (makes the whole thing more solid and prevents peeling of hooks) 0.3mm layer height 1mm linewidth Two walls Concentric top and bottom patterns. This is much faster than regular filling and is stronger lengthwise. Initial layer at 225°C, 30mm speed Normal layers at 205°C, 60mm speed, inner before outer wall; outer wall at 50mm speed Turn off all gapfilling and small line printing; we want just the main lines. Check in slicer. Overextrude a little by increasing the steps/mm setting for your extruder; mine was 95 for normal operation, now it's 105step/mm so the part comes out even more solid and the lines connect well. I'm getting six in a batch in 24 minutes, modifying your G-code to leave out the "eyes" of the hooks also helps with speed.
