As more people are finding this design and downloading it I thought i should add this note: I am not the original designer of this boat, I am a amature tinkercad user who had modified this design significantly.  With that said I have only printed two of these boats and although i haven't found any huge problems the quality of fitment of the parts, they are not up to standard with a professional CAD designer.  I am very open to remixes and suggestions/assistance to make this model better! 

Ok back to your regularly scheduled program! 
3-4-2023. Added a second option for the center piece for the lid. This part has a hole in the middle to mount a action camera with a 1/4 inch camera mount.  Use 9x5x2 oring top and bottom to seal. -Note, i have not tested this piece yet. Water test yourself before hand. 

3-2-2023-
- Updated front of hull so it sits flat on build plate- thanks uproar. 

- Added a TPU snap on cover (like tupperware) in 5 pieces. 2 frames, spacer, and 1 TPU cover printed twice.  If you have already printed this boat just cut off the poles that hold the original lid, fill in the holes then glue the frame in place just as you see it in the tinkercad image. Notice there is a taper and orientation to each piece. 
I RECOMMEND THE TPU COVER OVER THE ORIGINAL. 

11-12-2022 
 Added files for M-Jet 35 rear section to fit the brand new M-Jet 35 jet drive. Click the CG trader link below to find the maker of the M-jet 35. 
Also added two files for the seals for the m-jet 35 pump.  The seals are experimental currently. 


This is a 3d Printed jet boat i found on [youtube](https://youtu.be/WGhhtq-8DQg). I modified it in Tinkercad to fit the [Mjet30 jet drive](https://www.cgtrader.com/products/m-jet-3d-printable-jet-drive-for-rc-boats) by MjetDesigns, a deal at $10!!


With my setup this boat gets up to 25mph on a 4076 2000kv motor on 5s. For its size this boat is pretty light (Around 7 lbs RTR) .

I printed my boat in PETG transparent for effect and durability.  
The boat is glued together with Bob Smith CA and Accelerator (accelerator improves strength) for anything with a big Gap, and I used Weld on 3 to plastic weld parts together where the seams are tight. The outside has a thin coat of Epoxy for sealing and durability. 

I had to use the turn fins to keep the boat from spinning out. There are other modifications I am making on it currently, I will post those when i can. 

The boat had a flat bottom front to rear, i created a keel (for lack of a better term) for it you can print and glue on if you want. I didn't find that it made much of a difference in handling. 

The battery mount is split in half for ease of print, or you can print it whole with supports. 

Any questions?  Print it, build it, throw it in the water and have fun!

Important notes!- Update April 2022
   1-Don't use epoxy.  Use Bob Smith Cyanoacrylate or Weld-on 3 (prefered). 
 I weight tested these wheels with 240lbs of salt for my purifier and it did pretty good until I hit the rounded curb and the wheel turned sideways and blew apart.(Damaged was expected) When i inspected the broken wheel the epoxy simply peeled off in a layer. 
 I tried the same thing with Weld-on 3 and it Welded the plastic (PETG) together and removed chunks from each half, a much stronger wheel. 
   2- Use axle spacers to take up the side to side play on the axles.  The bearings are a good fit but after continued heavy use they will work out of the bearing races. You could also try superglue, but be careful not to get it into the bearing. 

Remixed an excellent design and added a bearing race to improve load bearing and lower rolling resistance. The only bearings i could find that fit the application somewhat close were these i found on amazon.

12mm x 28mm x 8mm bearings.
The axle shaft is slightly smaller than 12mm but its not a machined surface so there isn't a bearing that fits exact AFAIK.
The fitment will still be tighter than worn plastic wheels.
I print my wheels in PETG with enough walls to make the spokes solid. I am using .28 layer height and a 0.6 line width. These wheels are printing in about 2 1/2 hours for each piece.
I'm using a bolt to line up the wheels and epoxy to secure them together, tighten a washer and nut down on the bolt to hold them together for drying.
Good luck, Enjoy. 
Note, I have printed two sets but haven't assembled them yet. If there are any changes needed i'll post it. 
EDIT-  All 4 assembled and on the wagon, they fit awesome and roll soooo smooth.  Video to come! I opened up the inner part of the wheel (using a drill)slightly larger than the bearing race to free up the wheels for an easier pull. 

The bearings are a perfect press fit with my fingers. If you use PLA it will likely make the hole too small so you would need to adjust the wall inset to get desired results.

I remixed this to add a couple of screw holes to attach to wooden mounts for the wall.
