My 3 year old fell in love with Hot Wheels Track Videos, so I've been looking for cheap track in Thrift Stores. Found some track but no connectors.
Thingiverse had a nice track connector, but it was too thin for me, my 3 year old would pick up the track and the connectors would snap.
I remixed the design to thicken it up as much as possible, also made it a bit shorter so I can print on my Makerbot Mini. The connection isn't as flexible as before but they are much stronger which is better for my kid to enjoy!
Posting the design for everyone to use.
