3D-printed crane, all in one piece and without supports. This model is quite complex, but easy to use thanks to its two lateral levers that give it full mobility. It's a skill game for all ages and very entertaining.

This model also features a hole in the back that will allow you to screw it onto a base, to limit movement if desired.

And the best part? You don't need any engineering knowledge to use it! All you need to do is move the left lever and lock it with the clip that also acts as a brake, and move the left leg to the side.

In addition, we have designed two more files, so you can practice your skills.

Printing it is easy. It's a medium-high difficulty print, but don't worry, we have designed the tolerances to make it easy to print at home. We recommend using normal PLA filament for a better printing experience.

It is a medium-high difficulty print. The minimum tolerances for this model are 0.35mm, in the base of the parts the tolerances are greater to facilitate printing, however, it is essential to have the first layer of printing well configured and the retractions well configured so that the parts rotate correctly. There are also 16mm bridges. Normal PLA filament is used, I do not recommend using matte filament as it causes the movements to not be as fluid.
