Lô cuốn tóc uốn (perm) – Hair (perm) curler

It's just a simple hair curler. 
Let me know if you'd like me to make you a bigger/smaller version of it.

I usually print them in bulk of 4 on my Ender 2 Pro, in vertical position.

Print suggestions:

1. Suggested Material: PETG, cause of it's resistance to the chemicals they use when doing a perm hairstyle
    
2. Nozzle: maker's choice
    
3. Parameters/infill: maker's choice
    
4. Layer height: maker's choice
    
5. Supports: not necessary, the bridges are too small
    
6. Adhesion: OPTIONAL: 2-4mm of Brim, if printed in bulk and vertical position (see img)
