Table leg bracket to attach additional shelf

Use tis to attach an additional shelf to any table with quadratic legs (for example an IKEA LACK table) more than 30mm thick. Attach them on the inside of the legs and cut out the edges of the shelf you want to use. If attached properly these should support a modest load, even when made out of PLA.

there are holes for screws and nails.Don't use nails for IKEA LACK. ;)
