Egg Mortar 3000

This model was made using onshape.

Materials:

2x rubber bands

250mm of thin rope.

i used 4080 type rubber bands but any should work. this can work without glue, but the rubber bands tend to flop around, so i recommend it.

using plastic eggs i was able to shoot about 5ft. 

also recommend adding Vaseline to the inside as a lubricant.

using basic speed settings, this took me about 5 1/2 hours to print on an ender 3v2.
