Custom 3D Printed Display Shelf. This shelf was printed in 6 parts on my CR-10 Smart Pro 3D printer. Each part took 14 hours to print and was printed with black PLA filament. There are connectors that go into custom made holes that help keep the shelf together. I made this for a customer and as you can see they used it to display their vintage NHL hockey cups. We went over the dimensions for the entire shelf to get all the teams to fit just right. Then I cut the shelf into parts so that I could print during the day and not night time. Overall it was a very fun project.
