CAD Drawing for Prototype - Japanese Ice Ball Maker

I need a SET of CAD Drawings that a CNC Machinist can use to produce a prototype. I will also need the drawings in PDF. See reference videos for design. The Ice Ball Maker is constructed of two pieces of 6" x 6" x 6" aluminum square bar stock that stack on top of each other with two guide rods holding the two blocks in alignment. The ice ball is formed from a 2.5" sphere. One half of the sphere is machined out of each block, so that when the blocks are stacked, the the sphere is completed in the center of the block. In the bottom of the 1/2 rounded sphere should be a small drill hole 1/8" to let water and air escape out of the hole as the ice melts and water collects in the bottom of the sphere. This way, the water can run out of the hole underneath the bottom block. On the top block should be the other half of this sphere with two small holes should be drilled diagonally into the sphere from the outside of the top square block. These holes again are to let out water and air as the ice melts into the sphere. On top of the top square block should be a 2" round ball used as a handle to lift the top block off. There are two bars that are inserted into the bottom of the square block. There are two holes drilled in the top of the square block to receive these rods so as to line up the two square blocks and the two half spheres perfectly. The two bars should be 1/2" in diameter. The bottom end should fit in a recessed hole 1" deep and then thread into a hole at the bottom of the recessed hole another 1". The top of each bar should be rounded so as to make inserting the bars on the underside of the top block easier. The holes on the underside of the top block through which the rods extend should also be rounded off so the rods more easily are inserted into these holes. I have included a few different videos as reference. Please message me if you have any questions. Reference Videos: [login to view URL] [login to view URL] [login to view URL] [login to view URL]
