Train Tracks compatible with Lego® Train Tracks

thingiverse

A set of train tracks compatible with LEGO® battery powered trains. My goal was to have more flexibility, so I designed curved pieces in different radii and length, shorter straight pieces, and a 67.5 degree crossing. - Straight tracks are identified by number of ties. - Curved track pieces are identified by radius in LEGO® dots and number of equivalent ties at R40 - Crossing are identified by the crossing angle. Prints well with either PLA or ABS. If you have a smaller print bed, try rotating the pieces 30 or 45 degrees to make them fit. I recommend printing at "High Quality" or "Fine" mode for accurate dots and a nice snap action with other track pieces. Print without support - support for the rail ends is built into the design. These support pieces will snap off easily (2 per track end). There are small pockets under the rail ends into which you can insert a small screw driver to pop off the support pieces. For the pieces which match standard LEGO® train elements, it is probably more economical to just buy them, unless you buy your filament on sale, or have some filament left that you just want to finish. A good source of information about LEGO® track geometry is here: http://l-gauge.org/wiki/index.php/Welcome_to_L-Gauge Update 2/17/2019: - Tweaked a couple of dimensions, to address some feedback I have received. The dots came out a bit too small for many people. I also noticed that the top of the rails was a bit too high. Snap action is also a bit improved. - Corrected a small design mistake at one of the rail ends which didn't affect the function but made it easier to print - Included snap-off support in the design for the rail end overhangs Update 5/19/2019: - Added narrow R24 and R32 curves on request. I never printed these, nor do I know if Lego trains can actually negotiate such sharp curves. LEGO® is a trademark of the LEGO Group of companies which does not sponsor, authorize or endorse this site
