Pot/tower for Catasetum ?

[ncapensis]

I've noticed people tend to take images of there flowering Catasetum with pots balanced on top of another pot or something . I've seen various versions of a tower to hold the whole plant up for display. I was thinking of making a stained glass tower/form to better display flowers. Is there a general size of pot for many Catasetum ? I guess I could over size a little and make the top part that holds the pot deep so there are more options. I'd like to work up to making a cluster of inverted dormant bulbs in glass, some acting as legs some just hanging. May look a little weird but so do Catasetum's
I think it would be nice to have a purpose built form.
Not sure what I'm going on about really , but I think Catasetum growers will understand
