Duplo compatible fully printable train wagon by nirgal

Last crawled date: 3 years, 1 month ago

My goal was to make a fully printable wagon compatible with Lego Duplo train set. I decided to replace steel axles (separately purchased) with printed ones.
Some notes on my default settings:
the frame, the platform and the hook printed with ABS (200um)
the wheels and the axles printed with PLA (200um for axles and 150um for wheels)
in my case supports were required for wheels only
print axles in pairs, they are thin and high (40mm) and slowing down the print may be neccessary at some point
the finished wagon is rigid, but be gentle while assembling (it is not difficult to brake the frame if platform connection slots are too tight)
sanding may be required while fitting parts together (wheels and axles, platform and frame)
axles are connected with wheels using super glue
The finished wagon is pretty light: 48g compared to 58g of original one.
The wheels need to be rotated before slicing of course :-)
