 To reduce weight the headshell and all other components (except for the ears) were printed using LW-PLA (lightweight PLA). This pla foams up above a certain temperature, which reduces its density greatly. There is a tradeoff of course, because as the density reduces so does the strength. Although in my experience even at 50-60 % weight (compared to "solid" PLA) it's still pretty tough and flexible.
-My typical post processing sequence for PLA prints is as follows. **Keep in mind this is just what I do CURRENTLY, and this is an ever evolving process and I do not claim this to be the best orcorrect way to do it!**

 You may need to repeat one or more of these steps (especially during sanding) depending on the print, and how fine of a finish you'd like.
+Print settings for LW-PLA I used (on modified CR-10S with a microswiss direct drive extruder):
+  * Extrusion multiplier: 0.52
+  * Print temperature: 225 C
+  * Print speed: 50 mmm/s
+  * Retract distance: 0.5 mm
+  * Retract as few times and as little as possible, otherwise the hotend may clog!
+  * Wall loops: 3
+  * Infill: 10 % rectilinear
+  * 4 top and 4 bottom shells
+  * Layer height: 0.2 mm

 This resulted in ears that are under 100 grams each, which made a huge difference in comfort.
+Printing LW-TPU can be a bit tricky as I learned. It has to be printed very slowly, and it sticks to the build plate extremely strongly, so it has to be removed carefully.
+Print settings (on direct drive CR-10S):
+  * Extrusion multiplier: 0.6
+  * Retract distance: 3 mm
+  * Retract speed: 35 mm/s
+  * Coast to end enabled, distance: 5 mm
+  * Layer height: 0.2 mm
+  * Wall loops: 2 (depends on the parts, the bottom part, up to the hole, has 3 perimeters with 0.4 mm nozzle, 2 with 0.6 mm nozzle, but above that only 2 (this stays 2 for the 0.6 mm nozzle as well unfortunately)
+  * Print temperature: 250 C
+  * Bed temperature: 45 C
+  * Part cooling fan : 50 %
+  * Printing speed: 40 mm/s (with the 0.6 mm nozzle this is too fast, especially for vase mode, had to halve it to 20 mm/s)
+  * Reduction of print speed for short layer times was enabled (otherwised the ear tips would go melty), was set to 5 sec, with a minimum speed of 5 %
