Time to slice your design and prepare to print it. Since you probably won't be using a lot of filament I recommend using 100% infill . Just to give the mask some substance, though, this is not necessary.

And like my previous 3D printing projects, you need to add a pause to the slicer so you can add the tulle. If you have the ability to add script (like you can with Simplify3D) you can use the following:

{REPLACE "; layer 2," "G28 Y0 X0

M0

; layer 2,"}

Now, with these masks, I highly recommend pausing after the first layer and putting the tulle down then. This is partly because the design isn't that thick anyway, so you don't want the tulle to show through the top layers, and also, if you have a design that has dimension (like my Sun or my Stars and Moon masks) you want to make sure you nicely sandwich the tulle so it is better to do this before the design gets smaller.

On to the skirt of the print. I recommend using one as it helps hold the tulle in place. So I think you should make it so it goes one layer higher than your pause. Since I pause after the 1st layer, I had my skirt be 2 layers tall. When it comes to offsetting it from your mask, you have two options. One is you offset a few mm away from your design (like I did for the Leaves and Dash mask). Make sure it is far enough away so you can safely cut the mask out but not too far that you don't have room to tape the tulle down on the printer bed. Your other option is to create a border in your design that kind of acts as a skirt. I did this for my Stars & Moon and the Sun mask because they weren't uniform and since they were kind of chaotic in design, the skirt kept getting in the way of how I wanted to cut the design out. So, instead, I created my own skirt. I also used a skirt that was offset by 0 so that I could guarantee the skirt was printed first when the printer started up with the 2nd layer.

Another reason the skirt is helpful is that your filament may ooze out of your printer head while it is paused, if that happens you'll have a glob that needs to go somewhere. The skirt will hopefully catch the glob so it doesn't interfere with your design. I made my skirt 3 outlines but just 2 is fine. I would do more than one to give it some substance. So, again here is a breakdown of the skirts I used:

Leaf and Dash masks Skirt:

2 Layers 3 Outlines Offset 5mm

Stars & Moon and Sun masks Skirt: 2 Layers 3 Outlines Offset 0mm
