Customizable train tracks - Improved

thingiverse

This is an advanced version of Customizable train tracks. Here are the main changes: 1. It's now a customizer! You no longer need to use OpenSCAD to generate tracks. 2. If you prefer, you can open the single file lego_duplo.scad in OpenSCAD, and you won't need to download any additional libraries. 3. You can create bricks, plates, tracks, and calibration parts. 4. Tracks have been improved to print without supports - improved knobs and long bridges (set geo use offset to No). 5. Some code issues that produced non-manifold STL files have been fixed. Version 2: 1. The default knob and stud diameter has been set to 9.4 (KnobD and StudD). 2. The default wall thickness has been set to 1.5 (BrickWallT). 3. A small chamfer has been added to the top of knobs. 4. Calibration parts have been updated: dynamic size depends on GenerateKnobsX and GenerateKnobsY, second track end. 5. TrackRadius has been removed, and Track Length is now used for straight and curved tracks (in studs). 6. Curved rails have been updated to Type 3, so length of 4 curved rails (30deg) equals 4 straight rails (see more here: Lego Duplo Rail Dimensions article 4.2).
