Use zip ties to attach your preferred bottle-rocket-launching bottle to this base. Your bottle will be tilted at 10 degrees from vertical for good launch height plus directional control. The base makes a much more stable platform.

Always follow all proper safety procedures, of course. If you don't know how to safely use fireworks, don't use fireworks. [/safetynagging]

1. Print launchpad. Should fit within the build envelope of a Prusa quite nicely. If your printer is smaller, you could scale it down quite a bit without compromising fit with smaller bottles.

2. Consume bottle of favored beverage. If it is alcoholic, preferably well in advance of playing with explosives. I suggest a 22 oz. Red Hook ESB, but any similarly-sized bottle will fit, and smaller bottles work too.

3. Secure bottle with zip ties. Please.

4. Aim away from people, structures, and flammable scenery.

5. Launch bottle rockets. Bask in the glee of explosives, even if the payload is small.
