Filament Shelf (Enclosure Needed)

This design is made for my ender 3 enclosure. I noticed that there is enough space above my printer. So I planned to store some extra PLA there. The Support is printed and I need two of them (MIRRORED). The pipe it clamps is 17mm in diameter. And I prepared a 635mm tube for holding the rolls since the tent is 635mm in depth.

I also uploaded the Step and CAD files in case someone needs to change the size of the model. You can find them here at http://www.3dmaster.cn/3d-models/

Also, if you wanna have a look at the TENT, I bought it here https://www.amazon.com/dp/B09Z2K7FPJ?ref=myi_title_dp&th=1
