To go on your cruise door. It uses four 6x3 mm magnet. The magnets are a slip fit so they should just go in without any problems. There is a pause in the print profile so you can put the magnets in. If it is not there, you can insert a pause at layer 24 (with a 0.2mm layer height).

It prints facedown so make sure your build plate is nice and clean or else the finish might not be that great.
