About this 3D model

I made a very simple IKEA Lack table leg joiner So I could use some 5x5cm lumber from my local hardware store to extend the legs. I found this to be cheaper and faster than having to print custom leg extensions which take around 6 hours to print each adding up to a whole day of printing compared to the 1 hour it takes to print each of these (0.3mm layer height) that adds up to 4 hours plus the time it takes to get the lumber if not already in stock
