tricky one.
Some of the better i3's come in large pre-assembled chunks. So yes you could dissassembly them. But the more you do the more you risk damaginf the wiring and connections.

Have you though about a delta ?
Very space compact, great for tall models and the bigger ones can always be uised as a small table when not in use :-)
Have a look at the tevo little monster: https://tevo3dprinterstore.com/produ...3d-printer-kit

To turn it into a table you'd just need to print/make a drop on top that protected the electronics - pretty simple.
Hell make the top strong enough and you could use it as a stool :-)

Here's a smaller one that'll do 360mm height : https://www.amazon.co.uk/FLSUN-Pre-a...9520326&sr=8-5

Has the advantage that the electronics are stored in the base - so even easier to tunr it into a stool/table :-)
Much cheaper in tha states too: https://www.amazon.com/FLSUN-Pre-Ass...9520497&sr=8-2
