Model Rocket Display Bases

In my vast collection of model rockets, I have several that cannot stand on their own three/four fins due to protrusions that extend below said fins. For some, I have created wall mounts out of PVC pipe and fittings to give the illusion of flying, which works great for those, but others - the smaller models, do not lend themselves well to that method. For those, I have designed these little display stands. I will add more designs, as well as photos of the completed stands, as time allows.

base1 and base1b are designed to display rockets that use Estes A sized engines.
base2 is designed to display certain older water/air powered rockets
