Card deck shuffler V2

This card shuffler is designed for a set of official poker card size cards (smaller size cards would work too). This design can be printed on FFF & SLA style printers with a build volume of 130 x 130 x 130 mm. UPDATE: August-21-2017After receiving feedback from a couple testers, I made a version 2. The shuffler now has: Increased max card sizeA feet under the card holder for stabilityClips to hold the roller in place (Some people had it working without the clips)However, there are still some things left to do: Make a better connection between the stops and the bottomsI Love to hear feedback from you! UPDATE: October-29-2018I`ve also uploaded the .STP files for those who want to edit the shuffler. UPDATE: July-5-2017I have been improving the design, I decreased the angle of the rollers and adjusted some tolerances.I would love to have it tested by someone other than me. If you would like to help me, please leave a message! To assemble the shuffler you will need: 1x = M4x16 bolt1x = M4x40 bolt2x = M4 nuts4x = O-ring (you can also use a rubber band, or a hot glue gun) for gripping to the 3d printed surface
