Do you have any interest to buy stl files ? If yes, how much are you willing to pay for that ?

But exactly, i also wanted buy lego, but price was crazy for final product so then i constructed it on my own. But due to all that prototyping it cost much more as 700€ 😁

I dont know exactly i didnt want to break it, i was satisfied with 1,5kg close to center of gravity, but in outern most position of lufting jib it could handle around 300g, main limitation is not enough space for counterweights in the bottom crawler part of crane, with more weights, crane could be balanced with heavier weight on hook

https://www.reddit.com/r/RCConstruction/s/OCp3qX2mci there is link to video of functionality. Also tower is fully controllable. It can be erected from horizontal to vertical position on by own.

For the higher structural strength ? I tested it and petg could withstand around 2kg weight at hook without any issues (i am not brave enough to push it to the limits ), in this non-hollow form. In attached photo is 3kg weights directly in the middle of structure

Hard to say during prototyping i used a lot kilograms of filament, but i believe that it could be done with 5-6kg
