About this 3D model

My second version photography light,this one is more professional , in the actual shooting ,it's really better than the first one so that i don't want to open it anymore.HHH Also,if you are going to print one or two,need to buy 55W COB LED（or others）,heatsink(with OD 172mm),a power supply（ LPC-60-1400 60W1400mA）and a light stand. my links for these goods: https://detail.tmall.com/item.htm?id=42626121727&spm=a1z09.2.0.0.daeO7I&_u=965kgh6b658 https://item.taobao.com/item.htm?spm=a1z09.2.0.0.daeO7I&id=537024679210&_u=965kgh687b6 https://item.taobao.com/item.htm?spm=a1z09.2.0.0.daeO7I&id=42437250078&_u=965kgh6a4b3 and the screws you will need M650mm Screws 2pics M6 Muts 2pics M38mm Screws 16pics 6mm Rods L:110mm 4pics
