LF stand for a Biocube 29 OBO

[1986CJ7]

Not the original one, I am looking for alternatives or DIYs.

Little background: I have two munchkins, one 4yo and a fresh one. Both love watching the clowns, but I have to make sure it's safe if they'd every think it's a good idea to climb the stand.

Also, I'd like to find something that I could easily mod without taking its structural integrity for a ride. I'm looking into storing all the extra bits and controllers in the stand.

Since this is my first cube, I'd love to be educated on the options.

Please and thank you,
M
