Fab Lab Tulsa (https://fablabtulsa.org) asked me to a design a boat for their "Boat Moat" challenge during Maker Faire, Tulsa on August 25, 2018 and I gladly accepted the challenge! After a week of design and testing, redesign and more testing, FLT1 (Fab Lab Tulsa 1) is ready to race.

FLT1 fits inside the maximum allowed dimensions of 8 by 5 inches, and, as required, is powered by a rubber band. Weighing in at a total weight of 60 grams (2.1 ounces), as can be seen in the video, it can really move. I tested my FLT1s using single rubber band, but...

As usual, I probably forgot a file or two or who knows what else, so if you have any questions, please do not hesitate to ask as I do make mistakes in plenty.

Designed using Autodesk Fusion 360, sliced using Cura 3.2.1, and printed in PLA on an Ultimaker 3 Extended.

Materials and methods

FLT1 requires a 10 by 15 by 4mm ball bearing (I used a ProtekRC PTK-10046 with the rubber seals removed), and a rubber band (I used a Guillow's 7 by 3/32in rubber band).

I printed my parts on an Ultimaker 3 Extended.

"Hull With Graphics.3mf" is the dual extrusion hull I printed in Ultimaker Yellow and Ultimaker Red PLA filament at .15mm layer height and 20% infill with no supports. I've included the file "Hull.stl" for single extrusion.

"Winder.3mf" is the dual extrusion propeller winder designed for use in a cordless drill (yes, cordless, please do not use a corded drill near water!). I printed this part in Ultimaker Yellow PLA (winder body) and Ultimaker Polypropylene (winder insert) at .15mm layer height and 20% infill with no supports. I've included the files "Winder Body.stl" and "Winder Insert.stl" if you want to print them individually and press them together. If you choose this method, you may need to slightly scale down the X, Y dimensions of the insert, or slightly scale up the X, Y dimensions of the body, in order to press the two components together.

"Propeller.stl" is the dual extrusion propeller printed with Ultimaker Yellow PLA and Ultimaker Breakaway (for support) at .1mm layer height and 20% infill with supports.

See the video for how I assembled my FLT1s.

Hope you like it!
