This is a 10" x 3" shelf for a pegboard I designed. It was too big for my printer to print in one piece so I split it into 2 sections with pins to join the sections. I had good luck using a soldering iron to join the halves. I have also provided the file for the shelf as 1 piece if you have a printer with a large enough print area

DISCLAIMER I had issues with my print due to print bed temp being too high so fitment wasnt great. I will reprint in the future and take better photos.
