Appz is a great way of gaining first Design experiences
In the last years “3D Shook” has established itself as a well-known 3D printing Database for consumer grade FDM printers. With “Appz” 3D Shook has managed to create a great online 3D design tool.
Premade shapes such as Keychains and phone cases allow people with little 3D experience to easily design their desired objects. A monthly subscription of 14.9$ is required to successfully use the tool however the free trial turns out to be a great way of gathering first experiences in 3D design.
