Firefly Serenity Extra Large Snap-Fit Model
by jwolee, published
I wanted to make an extra large model, and decided to use pins to connect the pieces together instead of using glue.
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 print in PLA, and had no issues with printing without a raft. However, if you're printing in ABS or you tend to get curling, you may want to consider printing a raft as well. especially on this models that go all the way up to the edge of the bed.
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.
