This is a basic joint for a side table made with 2 ft long 1x1's. The joint is a very tight fit when printed at full scale and may require some adjustments depending on how accurate your lumber is. for the tabletop I used an old piece of scrap metal from our family's farm. Considering filament and wood costs it was about 15$ in total and the wood can be stained or painted to preference. I tested the joint and it held up to 250lbs of weight (The maximum I tested).
