This is a big model. You need at least a 220mm build plate. If you scale it down, the hooks might not fit into the base. Unless you scale them after a test fit.

My wife wanted a bigger hook than the flower I made. So I went real big with a few hooks.

If you have a .6mm nozzle or bigger, go that route. It'll save some time. 

You can do a layer swap if you want to make it a bit fancier than a solid color. There is a ridge on the heart, so you get the border.

You just need 3 screws. then reprint just a hook, if any ever break.

minimum of 3 walls, at least 15% infill
