This Lack Stacker was created because I wanted a very strong way to stack IKEA Lack-tables without having to damage them by inserting screws or nails into them.

The model leverages the fact that the Lack's legs contain a threaded pole that is screwed into the table surface. The model will wrap around this pole and sit between the leg and the surface.

Three STLs have been provided:

• the STL with the 60 mm high spacer allows an Anet A8-printer to comfortably fit between two stacked Lack-tables (as can be seen in the photos).
• The STL with the 0 mm spacer can be used to just stack tables comfortably without introducing extra space (except the little bit of space introduced by S-shape of the model wrapping from the outside to the inside)
• the STL with the 100 mm spacer is there to show that the design also works when needing more space.

This design is very customizeable! This can be done either in Thingiverse's Customizer app, or by using the SCAD-file in OpenSCAD itself.

Update 2017-11-25: Cleaned up OpenSCAD-file to:

• Allow better preview in the Customizer app
• Add descriptions to the settings that can be customized
• Ensure that spacer heights lower than 20 mm did not result in an unusable model.
