Looks really good... except I do not have any lego duplos

Hi, my partners and I are working on a TSA project for school and were wondering if we could use your model.

I printed this for my daughter and she loves it. It came out perfectly and fit together tightly. This is a great model

printed the duplo version without scaling, but the top part does not fit the bottom part. It almost fits, but I would say that the opening in the top part is appx 1mm to small to fit. Using a 3DWOX 200.

Thank you very much!
a nice Duplo Model for my little daughter!
at the moment just the bottom part is ready and it fits perfect for the duplo figures.
Printing the top "cover" at the moment on my new renkforce rf100 (absolute beginner mini printer)


is this for Lego and Duplo or just for Lego or just for Duplo. And how come the lego bumper car is smaller in the pic. And one more question did you 3D print from a robo 3D printer? :)!

Very nice, great job.
for lego Knob is fragile , the character can remove knob when you put him inside, same problem with the whell when assemble top and bottom. For lego size , need to be printed at 0.1mm per layer for an maximum of solidity.
I've printed 10 bumper ! my son love that ! if you lose your job , go to work at lego factory at the RAD service ;)

Please always also upload your original design files.
Not just the STL export.
So it can be improved upon.
Thank you.

Hi Marcus,

Actually, I don’t think the original file contains much more than the exported mesh to STL. I’ve modeled it in 3D studio Max, and after several boolean operations its merged to a single mesh.
