Duplo Train Caboose

My Grandsons love playing with their Duplo Train.  It's amazing watching these young minds be creative at their play. I've designed and 3D printed many accessories to aide in their fun and in their creativity. They seem to love connecting as many train cars as they can to one locomotive. I designed and printed this caboose to give them more cars to connect and more ways to be creative.

 

The trailer is made of 4 different parts. 4 wheels are printed and pressed into the trailer base. The connector block is added to the trailer top and both connected to the assembled trailer base.  The assembled trailer is compatible with other Duplo Train car tops. The Caboose comes in two parts, the Caboose Body and Roof.  I printed all parts in PLA with the wheels in grey, the connector block in yellow, the Caboose Body in red and the remaining parts in black. I especially liked Bambu's new Maroon Red PLA for the Caboose Body.  I printed all but the wheels with 5 wall loops. This keeps the Duplo nipples strong. I and others have had them break off when printing with 2 wall loops. These models do not require the use of an AMS.

 

9/6/2025: I've had several comments that the Coupler is too loose and that the train car disconnects too easily. My latest prints seem to be loose also. I added a print profile for an alternate coupler that tightens up the connection.  I appreciate everyone's constructive feedback; thanks.
