The file 'Micro Maxx Model Rocket Launch Pad 3D Printer Model' is (stl) file type, size is 27.0KB.
Here we have a launch pad for Micro Maxx rockets. Print three of the legs, which should slide into the base. And print a few of the igniterMounts, though mine held up fine after several launches.
Micro Maxx rockets are designed such that the igniter goes in through two holes on the igniterMount. Then you slide the rocket down on top of the igniter. I made the mount so that it can slide in and out on the base a little so you can line it up, though honestly there's enough igniter there you could just bend it.
For a launch rod I am using some 1.36mm diameter piano wire I bought as servo rods for RC air planes. That works out to something like 7/128th of an inch...so it's probably actually 1/16" rod (8/128 = 1/16).
You can see it in action with several rockets starting at the video point below. The rockets featured in this video can be found here: https://www.thingiverse.com/thing:6649886
