These are fun rockets with boosters that extend on take-off. I designed two sizes and each contain two parts: the main rocket body and the exhaust that comes out of the combustion chamber – which is a mouthful so I’m just going to refer to that part as the ‘fire boosters’. (Hope that doesn’t offend anybody too much:)
3D PRINTING SETTINGS
Layer Height 0.2mm
PLA works great
15-20% Infill
Dimensions of Large Rocket: 4in x 2 3/8in
Dimensions of Small Rocket: 3 1/4in x 1 7/8in
There are two ways you can print these rockets (I included both in their print profiles):
Print the complete rocket: this prints great but if you want multi-color for the ‘fire boosters’ (and/or fins) it’s going to take some time (I found 8-10hrs)
Print the fire boosters first, print the rocket second pausing at layer height 15.6mm for the large rocket and 30.6mm for the small rocket, drop the fire boosters in and then continue printing. This method is much faster:)
In the print profile for the small rocket I included the complete rocket to print on plate #1. On plates #2 & #3 I separated the rocket from the fire boosters, so they can be printed separately (make sure to print the fire boosters first:)
In the print profile for the larger rocket I included the complete rocket to print on plate #1. On plates #2 & #3 I separated the rocket from the 4 sets of small fire boosters so they can be printed separately (again make sure to print the fire boosters first:)
Note: supports are needed for the larger rocket at the base around the rings for the fire boosters. I have included those supports in my print profile. (Also note if you are printing plate #3, I did not include supports in the fire booster chambers so that they are clear to drop the fire boosters in:)
Have fun printing these…they’re a blast 🚀
