Duplo compatible fully printable train wagon

thingiverse

My objective was to design a fully printable wagon compatible with the Lego Duplo train set. I opted to replace separately purchased steel axles with printed ones. Some key points on my standard settings: - The frame, platform, and hook were printed with ABS (200um). - The wheels and axles were printed with PLA (200um for axles and 150um for wheels). - In my case, supports were necessary only for the wheels. - Print axles in pairs, as they are thin and tall (40mm), and slowing down the print may be essential at some point. - The finished wagon is rigid, but handle it gently while assembling (it's not difficult to break the frame if platform connection slots are too tight). - Sanding may be required when fitting parts together (wheels and axles, platform and frame). - Axles are connected with wheels using super glue. The finished wagon is relatively light: 48g compared to 58g of the original one. The wheels require rotation before slicing, of course. https://youtu.be/WfGxFVOmLlc
