Description

The most fun part about 3D printers is that you can design non existed things. For me, Duplo is a great way to experiment with (And have a happy kid in the process). After the straight rails to test the compatibility and interchangeable with the original Duplo (see: thingiverse.com/thing:36017 ) I’ve taken it a step further. And here I present the hexagon railroad crossing. Fully compatible with the existed Duplo rails.

The bottom is designed that it fits Duplo in every direction.

If you like it and print one yourself, please share a picture. I always find it fun to see others using my designs.

Instructions

The hexagon railroad crossing in the picture’s is printed on a Felix in PLA with a 0.25 layer height. But if you want the ribs on the track with more detail a lower layer height is advisable.

The Slicer may complain about some hole’s or intersecting facets, but I’ve tested with Slic3r and Skeinforge/Sfact and they both create good G-code.

No support is necessary.

Brilliant! Have printed the hex and the straight. I think of beauty to watch print as well! Can you design us some corners please? The hex as revealed that I don't have enough track!

Now we need more Curves! Please! ;-)

I Made one and we had fun today using it. Being printed on a Cube in ABS it did need postprocessing. the print itself took about 10 hours - a long wait for the kids..... But it was worth it ;-) next request: a reverse brick (like http://www.peeron.com/inv/part... which we don't have in our inherited Duplo train set....

it is still possible to get those secondhand, i even would like to trade a reverse brick or 2 for a duplo hexagon. i dont have a 3d printer

papamaanbeer on December 29, 2012 said:

reverse brick could be bought second hand would that not bee cheaper easyer? i dont have a 3d printer maybe that explains my reaction ;)

How did you deal with the thermal shrinking?

satoer on December 29, 2012 said:

Never had troubles with thermal shrinking. I only use PLA, I think PLA has less shrinking problems. But like I said, I’ve never tried ABS.

Thank you for looking!

Hmm, back to Plan A: Try out blue sharpies on white PLA before extrusion.

Someone is just so lucky!

I want to get our Duplo out and play again. Trouble is the youngest is 11 and way beyond Duplo. However grand kids should only be 10 years away for the eldest!
