Duplo Train Car
Print Profile(3)
Description
My 4-year-old grandson requested I make a train car to look like one of his other toy train cars. I designed this for him to add to his Duplo train collection. The model includes the trailer with wheels and rotating hitch. The Car top can be used with the printed trailer or is completely compatible with the Duplo Train trailers. Also, my trailer is completely compatible with Duplo's tops.
The trailer is made of 4 different parts; wheels, trailer base, trailer top and rotating connector block. The 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. I printed all parts in PLA with the wheels in grey, the connector block and Car Body in yellow and the remaining parts in black. I printed all but the wheels with 5 wall loops. This keeps the Duplo nipples and connector post 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.
The Car body requires a small amount of supports that I manually assigned. I suggest printing the trailer with supports however they might print fine without. Both are included in the profile .3mf.
6/13/2025: I updated the profile to enable Supports on the trailer to improve print quality.
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.
