Connector for Hot Wheels track

This is a track connector for my son's Hot Wheels track. We bought it at a toy sale and some of the connectors were missing, so I designed this replacement.

It's an awkward print as it has bits that stick out on both the top and bottom. I suggest that you print it as oriented on a grid support so that just the retaining pin points downwards. Then the support can be removed relatively cleanly. I recommend a full grid support because the layer above the support is only 1.2mm thick.
