This is an EDF boat I designed after seeing RCLifeOn's video of his custom EDF RC boat. This prints in two parts and requires a print height of at least 240mm and a length/width of 190mm or so.
There are two models, Mk. 1 and Mk. 2:
I have printed Mk. 1 which is a joy to drive but a little on the small side for a pond with any waves as you can see in the video.
Mk. 2 was designed to be able to handle waves better and is better suited for the 64mm edf. I have not printed this version yet, but it should work flawlessly as Mk. 1 did. The main difference is that Mk. 1 is meant to drive on land as Mk. 2 isn't, but still could.
The servo sits in the back and attaches directly to the rudder. The top of the rudder is secured to the EDF. Make sure you use a 9 Gram servo that is waterproof as the servo is submerged during normal operation.
The bow and stern can be glued together with epoxy. The type I recommend is classic jb weld, steel-reinforced epoxy. Most of the screw holes are set for M3 and M2.
Use a rubber band around the lip of the Cover Bottom to create a watertight seal. The open portion where the motor/servo cables route can be sealed watertight as well using double-sided adhesive tape.
The two EDF models I used are below:
