Parametric Launch Pad

thingiverse

You can easily set up this parametric launch pad to support any size rod with matching leg sizes. I've personally utilized it with 3/4-inch legs to hold a 1/4-inch launch rod, and the results have been impressive. Simply acquire dowels for the legs, cut them to your desired length, insert a suitable launch rod, and secure a blast shield - you'll be ready to launch. Keep in mind that this pad is relatively lightweight, so if you're planning to launch heavy high-power rockets, it's recommended that you add some sandbags or similar stabilizers to keep the pad steady. Despite its limitations, this parametric launch pad has proven itself capable of successfully launching a wide range of rockets up to level 1 high power.
