3/8" Marble for the 3D Marble Maze

thingiverse

I printed a 3D Marble Maze, and needed a marble for it, so I made one. I've included two versions - one that is just a marble, the other designed to print without supports. The no support version is cut in 1/2 with the flat sides down, and a small pin to help align the two halves. I've also included the OpenSCAD file I used to generate both models. Print Settings Printer: Original Prusa i3 MK2 Rafts: No Supports: Doesn't Matter Resolution: .1mm Infill: 90% Notes: I left supports at 'Doesn't Matter', because neither 'Yes' nor 'No' is correct either - but it does matter. The full sphere will need supports, the cut-in-half version does not. I recommend a high infill, just to give it weight. I did mine using the variable layer height function in Slic3r Prusa Edition - using 0.3mm layers for the pin and lower parts of the cut-in-half marble, and slowly reducing to 0.07 layers as it reaches the upper parts of the marble to give it a nice smooth finish all around.
