Printed using a Mk3S+ on PLA, PETG as well as ASA-X on 0.4mm nozzle on 0.2mm layer hight, takes around 1.5 hours with default settings @15% Infill.
The author remixed this model.
The original version links Lack Tables side-by-side together. I made the remix to incorporate the additional width between the table caused by the Lack Stack print to stack lack tables on top of each other. The combination will allow to have the tables on top of each other fixed, as well as have them side-by-side fixed together.
Lack Stack I used is the version from @GBear (https://www.printables.com/model/292357-lack-stack)
