Fast Lane Track Connector

thingiverse

This is a custom track connector for the Toys'R'Us store-brand car tracks, marketed as Fast Lane in Canada and possibly elsewhere. The track packs lack sufficient connectors to set up the tracks in any configuration other than the one on the box, so I created these connectors for my son. They enable you to connect an unlimited number of tracks end-to-end. You can fit five of these connectors on the print bed of a small printer like the Monoprice Select Mini. Printing each one takes about thirty minutes at standard settings. A strong and flexible material such as PETG is recommended, since these connectors will withstand a lot of abuse from an active child. I designed this connector in OpenSCAD and included the source file to allow for adjustments. The provided STL file works well for me, but you may want to reduce the size of the triangular protrusions slightly. I made the locking connectors larger than the originals to form a more secure connection. If your tracks have different tolerances, reducing the triangle size and increasing the separation by one or two millimeters might give you more wiggle room. I have no affiliation with Toys'R'Us or the Fast Lane brand of toys.
