I'm trying to upload a Thing-a-day this February. makerblock.com/2011/02/makerblock-thing-a-day/A Turner's Cube is a machined curiosity that used to be shown to a novice machinist. Their task was to (a) figure out how to re-create the object and (b) operate machinery with enough skill to re-create it. http://www.cnccookbook.com/CCTurnersCube.htmlOther Turner's Cubes on Thingiverse: http://www.thingiverse.com/thing:1355 http://www.thingiverse.com/thing:1906Day 8: Turner's cube. thingiverse.com/thing:6003 Day 7: Cupcake XY autohoming GCode thingiverse.com/thing:6200 Day 6: Cupcake CNC Optoendstop Trigger for X Minimum thingiverse.com/thing:6191 Day 5: Things That Cannot Be Unseen. thingiverse.com/thing:6097 Day 4: Extruder to Stepper mounting plate. thingiverse.com/thing:6106 Day 3: A shelving unit bracket. thingiverse.com/thing:6001 Day 2: A mirror bracket. thingiverse.com/thing:6000 BONUS THING: A Helen Weight. thingiverse.com/thing:6024 Day 1: A bathroom hook. thingiverse.com/thing:5999
