A spile is used to harvest tree sap for the purpose of making syrup. Around February to April the sap starts flowing in the tree and can be harvested. A hole is drilled into the tree slanting upward at a 15 degree angle. Insert the tube into the tree and put screws in the two holes in the sides of the base. Screw in a 2 liter bottle and wait for it to fill. Boil down and enjoy.I intend to flare the top of the tube out at the base to get a better seal on the hole but could not figure out how as this is the first thing I've ever designed in cad. I also acknowledge that there is not a flat spot for a printing base. Hopefully either I or one of you out there who has a clue what you are doing will modify this so it's printable on a RepRap before my printer arrives.
