cults3d
This is a simple but effective tool-less, screw-less item to stack Ikea LACK tables. Simply print four per table and slot the legs into it. The design provides a robust and secure means of stacking one atop another.
I've only tested two high, but it may go higher.
I've uploaded two versions a looser and a tighter one. I used the tighter one and it needs some force to push the top table into the slot. There is a looser one too, in case your printer prints differently or you would prefer the option to more easily separate the tables later.
