I have used my Creality CR-10 Mini printer and 1.75 mm Green and White PLA filaments to print the parts. It took me about 5 hours to print the main body and around 2 hours to print the front reflector.
My settings are:
1. Print Speed: 60 mm/s
2. Layer Height: 0.2mm ( 0.3 also works well)
3. Fill Density: 25>#/p###
4. Extruder Temperature: 200 deg C
5. Bed Temp: 60 deg C
