I have finally managed to create a curve track from the straight track by rbwendt using only Tinkercad! Its been a challenge trying to get this to work.This is for all those people with little ones who love Thomas, but they don't feel like buying too many sets and wasting money on retired items. If you own sets from the newer Adventures and Trackmaster Push Along ranges, using the right adapters will allow you to connect this track to your sets. I recommend using this one for connecting to Adventures: https://www.thingiverse.com/thing:3074865
There are four stl files:
curve.stl: The regular curve. curve_flipped.stl: Flipped. This is because the official tracks are double sided, but this one isn't. small_curve.stl: A smaller curve from a failed attempt. Not sure what you would use it for. small_curve_flipped.stl: Ditto.
Just so you know, this track is compatible with engines from the ranges:
Take Along Take N Play (both versions) Adventures Trackmaster Push Along Select Brio / Marissa and Doug / etc. wooden trains Select ERTL Thomas trains
This is NOT compatible with:
Trackmaster Motorized Engines Motorized Railway MINIS Other very large/small trains.
Thanks for looking at this! Likes are appreciated. If you have any questions, feel free to ask away in the comments!
