2 drip tips with cute Squirrels sitting on them.
update. bottom was too large for the gasket, so I've modified it

1.5

100

printing with 100% infill at this size is what gives it the strength.
Due to the limitations of my printer, some trimming is necessary to size to 510 connection

I took the Drip tip by gallowraven and seperated out the mouthpiece and fixed it's geometry. I then got the squirrel from his source (MBCook). I used a cylinder to cut the initial hole in the Squirrel, joined the fixed mouthpiece and made adjustments for bad geometry.
This included fixing the internal cylinder that was going beyond where it should join the Squirrel. Deleting each face and then re-filling them to join the model.
It worked so well, I decided to do the same with mikebattaglia's model too.
Blender was used to import and modify the models.
