Xmas Vacation Eggnog Mug http://www.youtube.com/watch?v=fKncYRJQRC8 Oh yes, I am not cooking or heating anything in this and do not intend to let any contents reside in it for very long. I intend to hand wash them after every use. After making a couple I decided to revise this and created a second larger version. http://www.thingiverse.com/thing:70309 Print the mug and two antlers (brown ABS if you have it or color it later). Clean up the tapered dovetail features until the antler tenon slips in & locks over the bump at the bottom of the mug's mortise. Print at least two, one for you and an associate - or as many as you need. I included an antler stl oriented flat since it was oriented oddly for printing when I drew it, you only need the flat orientation - structurally the dovetail feature would be stronger in this orientation due to the graininess of 3D printing, but mine are strong enough in the flat orientation and they were easier to print in the flat orientation. Darken the eyes and nose with a colored pencil or by some other means, which will not be dissolved or wash off with a seal. Seal for leaks with a wash of acetone and/or abs juice. For storage between eggnog times, the antlers will slide off and nicely fit inside. CAPACITY: These comfortably hold 100 ml (3+ oz) with brim room for walking about.
