Filament in a Bucket Storage Stand-off

I currently store my open filament spools in 10l buckets with silica gel at the bottom. 
To prevent the spools sitting directly on the silica I designed these two standoffs.

When I was almost done I found some similar models for the same usecase 
here on printables ...

So the hole design is more like a little play to train my Fusion360 skills. 
But maybe someone finds them also usefull, so I upload them here.

Diameter: 200 mm, height: 15 mm
There are two version a provided in different styles.
