Many use Ikea lack for 3d printer setups. With these brackets you will be able to add some rigidity to the table with using 30mm diameter tube. This does not increase the max weight capacity of the table as the table is just cardboard mostly. Use 245-246 mm length 30mm diameter tubes between connectors. You may wanna use glue instead or with screws to attach evertyhing. Cardboard does not hold screws that great.Easy to draw but if you feeling lazy.
