Time to prep your designs for printing! This is very important.

You will have two separate prints.

I'm using Simplify 3D but all you really need to be able to do for this print is get it to Pause at a certain layer and move the extruder head out of the way so you can put down the tulle.

Another very important thing to keep in mind here is a skirt. I like to use it when I use tulle (both so it can wipe any filament that has oozed and to help hold the tulle in place) but you can't use it for both prints.

For my print, I had some issues with filling in so I decreased my Outline/Perimeter Shells to 1.

Lastly, make sure you put the print somewhere on the bed it will be the easiest to add the tulle. So, not too close to the HOME point or too close to an edge.

Pause script:

{REPLACE "; layer 6," "G28 Y0 X0

M0

; layer 6,"}

Snowflake:

All you need is a pause halfway through the print and to leave out the skirt. I repeat, NO SKIRT.

Border:

You again need a pause halfway through the print. Here you can use a skirt. It isn't 100% necessary or anything, but if you want to use one, this is when you can.

If you can, look at the way the extruder moves around the print. You don't want the extruder going across the center. It looks like it should be good to go, but I also checked the Travel Moves and checked to have it Avoid Crossing Outline for Travel Moves to see if that will help.
