This is a SUPER tiny cat I made for my wife in cad because she likes tiny animal prints. It will print on a .4 nozzle but you really need to make sure that your Z height is tuned properly or it will let go of the plate. On some machines it needs to run slowly others itll do fine fast. So far thought its printed just fine on a Kobra go, an Ender, a Mega X and an A1.I've also used both pla and petg to print it.
