Wood train track connectors

thingiverse

I needed connectors for female-female connections and the original tracks came with too few. Looking through thingiverse collection of these connectors, none fit these tracks (I guess there are too many brands with slight differences) either because of connector length or hole size. I decided to make my own with options that fit tight.The track dimensions that I have [mm]:track width 39.5, height 12pin radius 11, neck width 6, length 17.5hole radius 12.5, neck width 7.5, depth 18.5One of the images show flex range compared to the original pin. The tightness is ensured by small protrusions (about 0.4mm) that are round and only in middle. This allows the tracks to flex a bit in all directions while holding the pieces together by themselves. Asymmetric pins are there to turn male-female track into male-male, still loosely attaching to other parts.Keep in mind that the pins wear down a bit with use as the contact point is small.
