I hated the base that comes with the Stomp Rocket toys. It seemed to always fall apart and just never was all that strong. I decided to quickly come up with something new that is hopefully a lot more solid and ready to go out of the box.

This is it.

I split it into two parts for two reasons. First off for printing, makes it easier to print without supports. Second, if you omit the post, you can use it on flat hard surfaces like a driveway or sidewalk...

You can either drill the design to accommodate the carriage bolt and wingnut that hold the tubes together, or in my case, I just super-glued them. Other than that, fit the hoses nice and snugly.

UPDATE and NOTE: My Brother in law also has a similar Stomp Rocket and ran into the same problem with the base being crap. He printed a version of my design and was asking why things didn't fit very tight. As it turns out, we measured hose and tube diameters and they are slightly different! SO, even similar products from the same company are made differently. No promises it will fit yours, I would suggest a fast, low res print with minimal infill to test things out. You can then scale as needed to make the final version.
