Summary OK, THIS NEEDS TO BE SCALED UP probably around x2!! large prints, but should be fun :) started with a conversation on Facebook's 3D printing group - (https://www.facebook.com/groups/makerbot/) started out as a taco truck that was for sale and everyone trying to figure how to design and edit to make it 3D printable.. Jim Carter took some designs here off thingiverse and made a taco truck by blending then together.. link to item he did - http://www.thingiverse.com/thing:1719548 But, then we all started branching off and taco train idea came into being. one of the complaints was most people want more than 2 taco's (I mean, well ya!) so I made the large car holding 6 :). I'll do another soon with just 3 or 4 so people with not so huge printers may be able to print.
