Ctan

I have exactly the same story as you. Rarely used from time to time with my kid and displayed on the shelf. It rotates smooth only one direction, second is almost impossible and clutch gear is ticking loud. I didn’t figure out what causes the problem but I’m planning to take it apart, clean all the bricks and rebuild.

For sure these wheels you’ve designed will be extremely useful for making longer carts with moveable carriages to pass the track curves. Thanks a lot!

It’s definitely worth to try because my kid still prefer duplo than system stuff. Wheel with pinhole is awesome idea! Thanks for that spark to reanimate this duplo/technic train idea

Thanks! :) anyway it would be great to replace pulleys with 3d printed duplo wheels because it’s impossible to get the right distance to fit the tracks. My train work good only on closed loops. The intersections are rather problematic and it sometime can derail.

Hi, here's what I've found - it's probably latest version I have. https://bricksafe.com/files/Ctan/duplo-technic-train/train-1.0.io Have fun

I'll look for the files this week, they should be somewhere as far as I remember.

This videos sometimes can be very informative in case of new sets (but then mute button is your friend)

Get a tripod and try to put model in same place each time when taking pictures. You can mark this place with tiny piece of tape or whatever you like. It helps a lot. Also grey background is pretty good for color balancing (I've tested couple of other colors and this one worked for me)

Hi, sorry for late replies but I really didn't have too much time recently. Thank you! I always wanted to build something like this, so my kid wouldn't scatter all the stuff from bed on the flor. Thank you! :) I have scifi truck in mind from the beggining of the project, because I like space theme. I have used your idea with the flex axle, it work pretty cool! Bed itself did not pull too much because of almost horizontal LA position at the start. But hey, it's only for transporting bricks, it can lift whole bed. I think you have seen them lot of times, but rather not in this context. They are pneumatic hose connectors :) I'm glad you like it, thank you for feedback!

No worries guys, I did this build mainly for my kid and he's the main audience :) I didn't have too much free time recently due to house renovation and I thought I'll do the pictures earlier. Unfortunately life revisited all my plans. I understand that deadline have passed. Only I can kindly ask if I can enter. If I'll be not allowed that's ok. Nobody will be sad I think. Rules are rules. I don't build stuff to win anything. My only win is to spent time on thinking how to connect all these puzzles to make nice stuff. Just because I like it. Contests are a great opportunity to get motivation and do something in busy adult life. So all in all, if yes it would be nice, if not I won't be sad. Just focus on the building guys! :)

Hi, @Jim I'm asking If I can put my entry to the contest because unfortunately I didn't have enough time to make it on time. Thanks in advance :) I mean this one:
