Mô hình vi khuẩn Streptococcus

Model of germ colony of streptococcus bacterium for biology class in primary school (4 grade)... but hope it will be useful later on too :)

Supports needed. I used organic, with 0,22 clearance and 30 deg of threshold for overhangs. 

I printed it with silk PLA, which gives it nice finish. 

Estimated size 15x15cm.
