Firefly Serenity Extra Large Snap-Fit Model
by jwolee, published
Total size is about 13" x 9".
I can get about 115mm in the X axis and 120mm in the Z axis with my TOM, and this model was scaled up to the max my machine will support.
I cut the model up with NetFabb, then used Blender3D to create sockets for the pins.

I'm currently in the process of printing this. It's coming out pretty nice and I'm planning on trying to paint it when it's done. My print quality was much higher on one piece so it doesn't snap together perfectly but it's still really great. No warping in the verse can stop me
You can also just turn a can of air upside down and shoot the part with a bit of it. It comes out super cold this way and causes a quick but brief contraction of the plastic and the part usually pops right off.
I've been doing the same. Easiest way to remove well-stuck large prints is to put the bed in the freezer for a few minutes - the plastic and glass cool at different rates, and the part pops right off on its own. I learned this the hard way after a very large part (~11" x 8") wouldn't let go and I cracked my bed trying to pry it loose. Now every print visits the freezer!

All parts printed with 1 shell and 5% infill, except for the pins.
Part1: Full Supports
Part 2a: External Supports
Part 2b: External Supports
Part 3a: No Supports
Part 3b: No Supports
Part 4: External Supports
Pins: 1 Shell, 50% infill
Part 1 was a bit difficult to clean all the supports, but have a thin file helped greatly.
Don't push the pins in too hard -- I accidentally pushed one all the way through inside the model. If it doesn't fit, either scale the pins down slightly, or try to enlarge the holes a bit with a file or blade.
