Melon and pumpkin support

This is my first ever model I designed in 3d. 

I had the need to keep pumpkins off the ground in our backyard garden, so I designed this model to be heavy duty enough to hold the weight of a pumpkin, and melons. So far it's working as intended. The spikes are in a separate STL file because they would turn the model into a stringing tower. I found it was easier to print them separately and glue them after.

I included the Fusion 360 files so you can adapt it to the size you need, or remix the model.

You can open the parameters dialog in Fusion 360 (Modify => Change Parameters) and adjust the sizes to your liking.

Post you makes and constructive criticism, I will try to improve according to them.
