Imagination flows when barriers are broken down. So, I busted down some walls between my son's different toy sets. He REALLY wanted a train car that his minifigures could ride… so, voila! The Mandalorian always wished he had it this nice. 

This train car should be compatible with all standard magnetic train cars. I've updated the design from the pictures to better enclose the M3 nut to try to prevent choking hazards. Please read the instructions below for assembly information.

INSTRUCTIONS (PLEASE READ):

In addition to filameint, you will need:

• 6mm x 2mm round magnets (QTY: 4) 
  • ALT: 6mm x 4mm round magnets (QTY: 2)
• M3 x 26 (or longer) screw and nuts (QTY: 2 ea)
• Loctite (optional)
• Super glue/CA glue

When printing the wheels the printer will pause. Insert the M3 nut in the hex space and MAKE SURE IT SITS BELOW THE TOP SURFACE. If it's sticking up at all your nozzle could crash. I am not responsible to any damage (unlikely) caused to your printer by failure to seat the nut flush.

When printing the hitches the printer will also pause. Insert two of the magnets into each hole.

• If you want to chain multiple printed cars together, make sure to reverse the polarity on the magnets. I accomplish this by inserting all 4 in a stack together into one side, then pulling off the top two and flipping them over before inserting them into the other side. 
• Please see the warning above about making sure magnets sit flush or below the top of the print. 

When assembling the car, put a dab of Loctite or super glue inside the threads of the nut to lock it onto the M3 screw axle. A jam nut with a longer M3 screw can also be used. Insert the hitch pieces into the underbody, then superglue the top carriage to the underbody.

If you have any questions, or if you'd like to see a design that doesn't require glue or screws, comment below! If demand is high enough, I'll revise the model. And I'll be happy to answer questions or clarify as needed. 

Happy printing!
