Pretty rough, and figured out after I printed it that if I want it to work with the original tracks, I need to offset the connector, and I need it to ramp up the opposite way. Will be re-working and uploading a different version sometime soon I hope. Thanks to markcosmic for the connector portion of the track. http://www.thingiverse.com/thing:330741.Needs to be printed with support - I printed it this time laying flat, going to try again not lying flat to see if it prints less rough.
