Bottle Rocket Wheels!

thingiverse

Time for some fun!!! Water bottle rockets! Next stage, Fins and weight optimization.... https://youtu.be/dkMXWTszbXw I've added Fins!!!! so check out the new Rings and Fins!! Videos to come. If you have any different bottle sizes, let me know, and I'll endeavor to put some more sizes up. Custom Section Time to play! 1.25L soft drink bottle 5mm sticks cable ties long stroke bike pump football pump spike Hot glue!! Any resolution with no supports.. Print 2 of each wheel, and 2 Rings. If you want Fins, print the Fin Rings version and 3 fins. Use the 0.1 version for 0.1mm layers, the other is if you want to print higher than 0.1mm (the 0.1mm version is just a little thinner and lighter). Print with the cut out on the fin up. Smaller wheels are for the back, closest to the water jet. Hot glue in place, small bead in 3 or 4 places should be enough. Drill a hole in the lid as shown. I started at 2.5mm and ended up at 5mm diameter. The bigger the more power. Use 5mm sticks for the axils and cable ties to hold the wheels on! Stick the Fins on with hot glue and a length of 5mm stick through the hole if desired. Make sure they are straight!! A Ball pump spike, with foam for a seal works a treat to pump. Pump to desired pressure. I recommend starting low...
