Pretty simple concept. Either find a stud in the wall to mount these on or use wall anchors. Line up the table with the brace held in place, mark 2 edges on the wall with a pencil. Do again for opposite side. Move table away from wall, line up marks, and use a long pencil or screwdriver to reach into the center hole and mark the wall. Add your anchor, screw them to the wall, then slide you lack table in and run 2 screws through each leg to secure them to the mount. Enjoy a nice, stable, wobble free lack table! I used PLA but PETG could also work. You want them strong, so 30+% infill and 3+ walls. You'll need to print two in order to secure a lack table to the wall.
