I am growing some plants that might grow beyond the height of the original Plant Support. I just made a simple tweak to allow you to stack additional plant supports on top of the original and keep your plant growing straight.

Designed with a .5mm offset (1 mm clearance) and a taper so that it seats firmly.

3/30/24 - I was having issues getting the legs to slot in properly, so I have uploaded a model with a chamfer and .2mm clearance.
