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'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!
In case you guys are wondering....I've stopped using rafts on a lot of things and gone to wonderful, beautiful Aquanet. I use the "All Weather" version that is fragrance free. While the bed is hot, shoot the bed with a coat and fire up the printer. Whatever you print will stick nice and hard and not curl up. And I do mean stick! My bed is covered by Kapton and the Kapton does not come up with a use a spatula to remove the print. Just awesome.....
Awesome work! Pins are a great idea, though if you ever do want to use glue, typical model superglue (the kind you find in hobby shops that sell miniatures) will work equally well with ABS or PLA, as will standard acrylic model paints. There is some major appeal to making something that's finished right off the plate, of course.

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.
