This is my sign, and means moon in 11th night from new moon. Or simply backside of crescent.
Also this was my first try to polish ABS. The polished ABS is beautiful like ebony.
I used 4 steps to polish the ABS. #240 sand paper, #600, #1200 and cloth with abrasive compounds. 10 to 15 minutes for each one to polish.
I am using DaVinci 1.0 3D printer by XYZ printing.
Layer pitch is 0.2mm.
Normal speed and normal shell thickness.
No raft. No support.
With stick paste(Tombow, Shiwanashi PIT).
15 minutes to print. 20 minutes for shaping, constructing and polishing.
Less than1$ for ABS.
