Ikea Lack Stacking Leg Extensions
75mm Ikea Lack stacking leg extensions
I plan to use these to enclose my Folger Tech 2020 i3 using two $10 Ikea Lack Side Tables, but you could stack these tables for any number of other reasons too.
The Sketchup file is included for those that would like to lengthen/shorten the leg.
I first saw the idea for using these tables as a 3D printer enclosure on Phatima's Instructable after some Googling.
