Reversal for easy fit 3d tracks

thingiverse

[update] the initial versions of the model files were upscaled. The ones available now have the correct scale --- My son was always trying to reverse the tracks (especially the curved ones) in order to create the layouts he wanted with the pieces he had at that moment, so I've designed these adapters for him. Those adaptors allow your kid or you (because I know you print these for you as well) to reverse the direction of turns, slopes, etc. Trust me, it will save you a lot of printing hours and material ;)
