Keeps those cards in slick sleeves from sliding around the table. Now sized to hold a Commander deck (aka EDH, Eternal Dragon Highlander) composed of 100 cards in sleeves. Still printable on a Thing-O-Matic.Just in time for those New Years Eve MtG games that will last from 2012 all the way to 2013.By popular demand. Plus, I wanted one for myself. Including the .blend file this time so you guys can have at it. Update- added .stl and .gcode for cardholder02, which thickens the sides by 5mm to make them stronger (the initial version broke in my backpack.) The 02 gcode also reduced my flow rate slightly, and was done with an extra shell for added strength. Though I do recommend compiling from the .stl instead of printing my .gcode, since every Thing-O-Matic is different. Version 02 is still printable on a Thing-O-Matic, though you'll probably need the build plate instead of the conveyor belt. Finished dimensions are 98mm W x 109mm D by 69mm H.
