Here's a simple string art design of a four leaf clover to bring you good luck. It was created using the maker world software. 

The print profile is for the A1 and its only one colour. You can still print this on the Mini just scale it to fit the build plate :) 

It has a hole so you can hang it up where you would like, I'm using mine outside in the garden. 

I hope you enjoy it and it brings you good luck! happy printing :)
