The reason I'm making them stacked is because of lack of space, can't do them separately.
Regarding the bottom cage, I'm adding 6 or even 8 wheels to the base to avoid sagging.
I'm not using IKEA wood on this, I'm using 12mm thick Plywood. What kind of metal bracing could I add?
I wanted to make a pretty double cage instead of 2 cages and a table or something like that. It would also be more affordable as well.
I have already invested money on the wood and cutting for this so I'd like to not waste all of that... What can I do?
