After considering buying a set of EZStudRack adjustable shelf holders for inside of a stud wall, I designed this Adjustable Stud Shelf Bracket instead so I have more options. This can be adjusted at 1 inch intervals using 3/4" thick shelves. It is exactly 10" high and can go on the left or right side. Make sure the angled extra support pieces are below the bracket so your shelves fit well. It is 1mm less than the 2 x 4 width, so if you are leaving sheet rock, you will want this a little wider by clicking on the object and click the scale icon; uncheck uniform scale and change the x axis size to the width you are after. You can also modify my tinkercad design at [https://www.tinkercad.com/things/adVUoWMq5VL-adjustable-stud-shelf-bracket-1-inch.](https://www.tinkercad.com/things/adVUoWMq5VL-adjustable-stud-shelf-bracket-1-inch.) I used PETG with a stronger setting to give it strength but PLA may also work. Enjoy!
