This time I'll make a 3D printed rc boat, the design can be downloaded from Thingiverse from its creator/designer called Wersy on Thingiverse. The rest of the steps are going to be described in this ...

You’ll also need to use supports, so expect to spend a fair bit of time cleaning it up post-print. The rest of the model can be printed at 0.3mm, which is going to save a lot of time on the hull.

His other solution, a quasi-jet engine-dual-hulled-boat is pretty fun too — he’s 3D printed a large impeller for his motor, and strapped it in between two of his boats!
