Bonjour,

Your duplo train design looks great, I'll give a try to the several wagon next days.
However I am a bit confuse about the wheel fixation : using a press you just insert the nail in it ? Does it works on the long term ? What kind of infill do you use for the wheels ? Did you tried it with PLA ?

Merci.

Hi, I am not sure about the infill, could be something like 20%.
The design works well with PLA. Take a nail and cut the head. Then press hard and it stays. There is a hole in the wheel which keeps it straight.
Must difficult is to press perpendicular, for that I have used a drill and a bolt to have an effective action as on the photo.
What is not perfect are some of the bridges which I would have to improve, Wagons are OK.
