My wife began asking that I design earrings for her and her friends. so I have created about 50 designs that I will slowly upload - so look for new designs! Most can be printed with a .4 nozzle but for extra detail you may want to consider a .02. I have printed these successfully on my P1S and A1 Mini. You will need earring hardware - i use the following kit from Amazon -- https://www.amazon.com/gp/product/B09YV65J75/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&th=1
