Water Rocket Fin Bracket

thingiverse

So the springs here, we all love water rockets, and i needed a fin assembly for my large rocket. nothing here had 4 fin brackets that i could find, so i designed this for you all. fits a 98mm Outer diameter bottle, scale up or down as you wish, it can be tricky to get the perfect fit! :-) Please use nylon bolts or screws when assembling your fin bracket, bottles under pressure mixed with metal is not a good nor safe combo!! The holes are made about 1mm in diameter for the screws, feel free to drill them to your exact specifications ;-) Did i mention that if you print two of theese 4 part assemblys, you will have a very good fin system for even a large rocket. They are designed with splines to be self aligning. Have FUN! Print Settings Printer: Fabrikator Rafts: No Supports: No Resolution: 0.20 Infill: 100 % Notes: Print at 2 perimeters with a 4mm nozzle, that gives a 100% solid model, 1.6mm thick total. use about 10 layers of skirt, specially with ABS so it doesnt warp or jump loose. took about 1 hour to print.
