Adapter for IKEA Trofast Boxes into Kallax (V2)

V2.0 Update: 

• improved strength
• distance helpers for the drill holes added (Thanks @ Mr. Basti for the Idea!)
• the distances between the drill holes of the new version 2.0 are not compatible to the older version 1.2

A simple adapter to be able to use the Trofast boxes in a Kallax shelf.

Printed it with PLA. PLA was also used for the support. This was very easy to remove from the print.

I fastened them with so-called “Euroschrauben” (6,3 x 13 mm). Due to the thin furniture material, I pre-drilled with a 4 mm drill bit.

How to use de distance helpers (they are compatible to version 1.2 and 2.0) :

For easy assignment, the desintance helpers and the adapters are labeled “A” and “B”. Arrange as shown in the following picture.

I recommend assembling the components on the floor and then temporarily fixing them in the kallax with adhesive tape.
