IKEA LACK extension

I created the extension to allow my growing children to fit under the LACK table. I didn't want to shorten the [chairs](https://www.ikea.com/cz/en/p/kritter-childrens-chair-white-40153699/) 😁.

I have tested the extension on [LACK (Coffee table) 90×55 cm](https://www.ikea.com/cz/en/p/lack-coffee-table-black-brown-40104294/) and [LACK 55×55 cm](https://www.ikea.com/cz/en/p/lack-side-table-white-30449908/).

Extension lengths are from 20 to 120 mm in 10 mm increments (I used 40 mm).

I print from PLA and the last 2 mm from TPU to avoid hard contact with the floor. But you can print the whole thing in one material.

When using longer extensions be careful of the length of the screwdriver.

I used 4 × 25 mm wood [screws](https://www.obi.cz/vruty-do-drevotriskove-desky-a-univerzalni-srouby/lux-vrut-se-zapustnou-hlavou-pz-plny-zavit-zlute-pozinkovany-200-ks-4-x-25-mm/p/3939907) for the attachment.
