Is there a weight limit for large prints (V3 KE)?

I have an Ender 3 V3 KE and want to print a large print. It will weigh about 300+ grams. Should I make any adjustments to speed or anything? It seems like printing at normal speed will mean a lot of stress when the print is close to done.

I don’t think weight is the problem more a worry is shape and material choice.
