Creating custom stl files for charity merch (support/designers needed)

Hi Guys!

I’ve just purchased a Phenom L for my Charity and im looking at designing some CUSTOM MERCH.

As i’m new to 3D printing, creating custom STL files so we can print custom merch for our charity is a daunting task.

Would anyone like to support in helping us design custom merch?
