![]() ![]() See the attached picture for original screw, as well as an idea that might work without filing. Perhaps it's possible to file off the upper threads one some screw? Springs is not critical for the basic mechanical function. The screws needs to have threads only in the part which screws into the axis, so the center pieces can rotate freely. I've made individual files for every part, some cleanup, smoothing and drilling is probably required. The challenge is to deal with overhangs, find a good solution for the screws and springs and of course make it rotate well. cube_WIP.wings features a assembled cube for test fitting the pieces. Modeled in Wings3D original sources files included. Would love feedback and thoughts on this. 2010 - Robo printed the first working cube!ĮDIT5: "v4" Updated the corner piece with smaller connection part and beveled edges/smoothing (polygons went from 67 to 3432). All new objects combined in one Wings3D file for less clutter.ĮDIT4: April 17. Scaled 10x from before.ĮDIT3: "v3" Side piece turned the right way this time. Files updated.ĮDIT2: "v2" New side and corners, resting on side. I don't know if it matters much in 3D printing? The flat sides on the pieces are 20 Wings unit wide/high/deep, which should equal to 20mm.ĮDIT: I split the side and the corner (diagonally) in two parts to make it printable, but it needs to be glued together afterwards. My 3D background is from image and animation rendering, where it's important to maintain quads and avoid many edges meeting in a vertex. When the cube is functioning mechanically, perhaps we can distinguish between the sides without colors? See corner_color for an example. Feel free to modify anything so we can have a printable, working cube. I don't have my own printer, yet, so I'm not able to test this model myself. Thank you very much Robo!
