Here's my collection of 3D printed Judaica designs.  These parts were designed with 3D modeling software (Fusion360OpenSCAD or ZBrush), prepared for printing (using Simplify3D) and then made on a 3D printer (MakerBot Replicator 2) with PLA plastic filament. They can be viewed on Thingiverse where the design files can be downloaded for free. Clicking on the photo will take you right there.
