A train for young kids to play with that has stackable elements. Assembles without glue.
You'll need 6 wheels and hubs for an engine, 4 of each for the car. the engine and each car will hold 3 blocks high.
Minimum reccomended print quality settings: 0.4mm nozzle, 0.2mm layer height. 3 walls, 6 top/bottom layers, 15% infill.
Support is only required on the car under the connection point, but some drooping will occur in the holes for the hub. This did not affect my ability to press in the hubs though.
The author marked this model as their own original creation.
