Chân đế bút vẽ (Đế vuông)

I created a Paint Pen Holder with a square base to clean up my workspace and organize the paint pens by color.  I designed the model using Fusion360. Simple rectangle base 145.5mm x 56mm with a 2.85mm height with 24 Tubes (15.5mm inner diameter, 17.5 outer diameter, and a height of 45mm).  I printed the model on the Creality K1 printer in Creality Hyper PLA. I did not select supports or brim.
