Duplo™-compatible straight track segment

thingiverse

Pretty close match to the latest official Duplo™ straight train segment. I have tested it and it works fine. I did not get the jigsaw connectors *exactly* right - they fit fine, but the tolerance is slightly higher in one direction than the other. Only an issue if you're a perfectionist. In any case I included a Solidworks model so you can easily modify it.
