I like the idea of the design and I wish it would print. The files are all over the place. V7 Holder and V7 Gears are very poorly arranged and are not all situated to be flat on the bed. Only one half of the holder in able to make contact with the bed the other half starts the print on the 2nd layer. The gears only the holding pint start on the bed, some of the gear don't start printing on the bed till the fourth layer. As the designed has grouped the various parts as one STL and not just uploaded every part individually it make it almost impossible to print. I would like to say its a good design but it really isn't at all!
