so i built this a few years back, but now that im going to college, my parents are making me get rid of it because it takes up too much space. it comes in two pieces, the box and the slope part. the slope is 12x3 i believe, the box is 6x3x3. its portable so its nice because you can take it down and move it out of the way. after the picture i added pvc pipes across the whole thing to make it faster. if you dont want those they will easily come off.
im in west seattle, if you come pick it up its yours. if not, its going to the dump/firewood on August 15th
