Alex drawer extender adapter

Are you like me who hate the IKEA Alex drawers for their lack of space-efficiency? Tired of not be able to use the 10 cm of space in the back of every drawer? Look no further! This is a simple way to extend your Alex drawers so you can use all of the space inside them What you need is a Router (plunge router?) uncartain about the english word for it. A jig is added to make it easy to cut the screws to the right lenght! Just add a M4-nut to prevent damage of the threads.
