ThinkFun BoatBuddy Expansion Set Upgrade

thingiverse

UPDATE 11/4/2015 With my cheap purse i3 printer, I managed to print it without that much difficulty. I uploaded pictures of my BoatBuddy and I scaled the files except the mast 105% and the mast has been extruded up by 2mm for the paper to be held in to the mast. BoatBuddy has a hole on top of the float where it is compatible for the rod from Thinkfun to be connected. In conclusion, this is will be a work in progress since it is completed, unless you have some issues, comment it. And also, I will show you my print settings. **MATERIALS BoatBuddy x 1 Mast x ? (minimum 2) Connector x ? (the number of masts printed - 1) Tape or glue that doesn't dissolve in water. A Macaroni and Cheese box (7" x 1 1/4" x 3 2/5") Index cards or 3" x 5" papers x ? (the number of masts) ** This is BoatBuddy to upgrade your ThinkFun set to conquer your land and sea. BoatBuddy comes with a float that supports a 7" x 1 1/4" x 3 2/5" box (a macaroni and cheese box) and you can use make it float on water or you can modify your car to run on wind power and better yet, why not do both? INSTRUCTIONS 1) Locate a clear spot inside the box where the mast will come in and out from both sides. Make a hole but NOT TOO BIG just enough for the mast to go through. 2) The mast can extend to your desire but you don't want it too high or else torque (lever: the longer it is, then it will use a lot of force) will kill it and you will lose a BoatBuddy. A mast is 75mm per print and the connector (the piece that looks almost like a cube) is used to connect the mast together. There are two slits on the mast where the index card will go. Use the short edge to insert it (Hamburger style) and use tape or glue to hold it in place. 3) SWAG OUT your ThinkFun BoatBuddy/car/mobile and have fun!!! Print Settings Rafts: Doesn't Matter Supports: No Resolution: Rectilinear Infill: 20% Notes: You don't need supports since they are all laid down, but it's your choice. I USED SLIC3R 20% is strong enough but you can go below at least 13% infill to make it sturdy and not break when you try to take it out. I use 2 layers for bottom and 2 layers for top. But I recommend that you should have at least 3 for the top, because mine has some small holes where the float is most vulnerable at for it to sink. I used PLA because ABS sucks and can't stand the smell of it and the warp and besides, my heatbed broke and ABS is useful to make ABS juice for my PLA. First Layer height is .2mm and the rest is .15mm. AGAIN THIS IS WHAT IS USE, YOU CAN TRY TO USE YOUR OWN SETTINGS 2 perimeters Perimeter: 45mm/s Small & External perimeters: 70% Infill: 45mm/s Solid infill: 40% Top solid infill: 35% Support material: 30mm/s Bridges: 50mm/s Gap fill: 20mm/s Travel:100mm/s First layer speed: 30% Max print speed: 80mm/s
