lab vacuum line stand

Edit: I made one finally, and the fit between top and bottom required a bit of help from a hammer, but it fit fine. I also revised the interior support for the base as I previously couldn't fit the BB's in it, but you can now.

I needed a stand to rest the vac line against in the hood, so I designed this 2 part stand. The base is a shell with a center support in the bottom ring to support printing. I left the base hollow so that BB's or sand could be added to give the stand some weight. Once filled, the top should snap into the base, though removing it later will be tricky/impossible. This is still a work in progress, so any suggestions are welcome.

shouldn't need supports if you orient the parts on the print bed correctly. I will be printing this on the MP select mini V2, I have to scale both parts down to 97% to get it to fit the print bed.
